The title of our sermon this morning is You Are a Living Letter.  We are in 2 Corinthians chapter 3 verses 1 through 6. Now we know from prior sermons in our study of 2 Corinthians that false teachers have infiltrated the church at Corinth. False apostles, some have called them super apostles from the text of 2 Corinthians. And they are obviously these false teachers, these false apostles. They are obviously desiring to lead away disciples after themselves. They want to make a name for themselves. They're intending here to fleece the flock of God, so to speak, for profit. And as Peter says, by covetousness they exploit the Corinthians with deceptive words. They have secretly brought in destructive heresies, even denying the Lord who bought them. In 2 Corinthians chapter 11 verse 4, Paul infers that they are preaching another Jesus. Whom they have not preached. A different spirit. It's Paul, Timothy, Silas have not received. A different gospel which the Corinthians have not accepted. Peter says here, of this having a heart trained in covetous practices, they are accursed children having forsaken the right way and gone astray. Many in Corinth making shipwreck of their faith have followed their destructive ways. And because of these peddling hucksters in Corinth, the way of truth is blasphemed. Now in order to advance their wicked and destructive agenda, these false apostles in Corinth know that they have to undermine and marginalize Paul himself. Here again, Peter's description of false teachers in this sense is instructive. Peter says they walk according to the flesh in the lust of uncleanness, and they despise authority. They are presumptuous, self-willed. Peter says they're not afraid to speak evil of those in authority over them, whereas even angels would not bring a reviling word against them. And so they falsely accuse Paul. They mercilessly slander Paul. They twist his words. They assume the worst of his motives. And like natural, brute beasts made to be caught and destroyed, they speak evil of things they do not understand. And in the preaching of lies and in the slandering of the Lord's minister, these false teachers succeed, if you will, in enticing unstable souls. And by them these unstable souls are brought into bondage. Peter says that they are wells without water, clouds carried by a tempest for whom is reserved the blackness of darkness forever. Paul here calls them peddlers, hucksters, charlatans, snake oil salesmen, they're liars. And he clearly distinguished himself from them in 2 Corinthians chapter 2 verse 17 where Paul says, we are not as so many peddling the word of God, but as of sincerity, but as from God, we speak in the sight of God in Christ. As many in Corinth, through the efforts of these false teachers, begin to doubt the apostle Paul and question his apostolic authority, Paul's ministry among them in the gospel begins to weaken. Paul begins to lose some influence among the church in Corinth. He knows, Paul knows that if these wicked liars in Corinth are successful in undermining him, they also succeed in undermining and marginalizing the message that Paul is preaching. This can't go on without an answer, right? The stakes are way too high. This is the Lord's church that he purchased with his own blood. These are the Lord's people following Christ and preaching Paul's gospel. Their souls hang in the balance. In other words, when the gospel is preached, when the Bible is preached, it's not a mere academic exercise, right? They're not sitting here just to learn some nice platitudes, follow a nice example that'll help you lead a better life, a more happy life, right? That's not what this is about. This is about heaven and hell. This is about life and death, and your soul hangs in the balance. How you hear, how you listen, and then how you respond has eternal consequences. Now, Paul understands that. And so, Paul then, compelled by circumstance, he reluctantly undertakes a defense of his ministry. He does that for the sake of these people in Corinth. He loves them. He cares about what happens to them. And so, his message can't be marginalized. He, therefore, cannot be marginalized. And that's for the sake of these people that he loves. So then, we come to a question. We consider these things. What distinguishes them and authentic Christian ministry? What validates, if you will, the work of God's messengers? How do you know the difference between these false apostles, these false teachers in Corinth, and Paul? And what Paul is preaching? What Paul is doing among them? What differentiates the work of God from the work of the godless? And Paul, as he asks, who is sufficient for these things? In 2 Corinthians, this is Paul's second canonical letter to the church at Corinth. Paul erupts in praise in chapter 2, verse 14, that the Corinthians have responded favorably to Paul so far. He says, now, thanks be to God, who always leads us in triumph in Christ. He references the work of gospel ministry in verse 15 as the fragrance of Christ among those who are being saved and among those who are perishing. To the one, Paul says, it's an aroma of death. To the other, Paul says, it's an aroma of life. And then Paul asks the question, who is sufficient for these things? What follows, what follows, and what will be our great joy and blessing to study if the Lord wills, is a glorious defense, a glorious description of the Christian ministry, of the gospel ministry. And that defense, that description runs through chapter 7, verse 5. Notice with me, before we get into the text, the doors that sort of open and close this section of text. One door opening this section is in chapter 2, verse 12. Look at chapter 2, verse 12 with me. Where Paul says, opening this section furthermore, when I came to Troas to preach Christ's gospel, and a door was opened to me by the Lord, I had no rest in my spirit, because I did not find Titus my brother, but taking my leave of them, I departed for Macedonia. Next we have verse 14, and thanks to God for triumph. Flip over with me to chapter 7, verse 5. Chapter 7, verse 5, is a door, if you will, that brings this section to a close. Look at verse 5. For indeed, when we came to Macedonia, our bodies had no rest, but we were troubled on every side. Outside were conflicts, inside were fears. He comes back to the same subject then, right in chapter 7, verse 5. These are bookends, if you will, on this section of text that runs from chapter 2 into chapter 7, and it's this wonderful section of theology that deals with the Christian ministry. As we look at chapter 3, verse 1 today, it's like walking into a beautiful room, right? A lavish room, a warm room, a room you don't want to leave. It's just stacked with glorious books on good theology, right? Glorious text that we're going to be able to study. It's a warm room, it's hopeful, right? It's convicting. At the same time, it's joyful and rejoicing. It's a room you want to spend some serious time in, and we get the blessing of the Lord Terry of spending several months here. And we're going to, this is going to be fun, right? This is a text of scripture that's going to be just a joy to go through. As we walk through this room together, Paul lays out a description of new covenant ministry, right? Gospel ministry. And this beautiful description, this beautiful presentation of new covenant gospel ministry is set in stark contrast against false teachers in Corinth. We'll remind ourselves of this as we work through the text. In the background, against the black backdrop of wickedness, those false teachers sit in stark contrast to the ministry that here Paul is describing with us today, beginning in chapter 3, verse 1. Many come, many come today claiming to be sent by God. There are many who preach in pulpits, many who preach on the radio. You can find their recordings all over the Internet. Many claim to speak for God. And many of those who claim to speak for God are lying, deceiving, clouds without water, by whom people are brought into bondage. Jude describes them as late autumn trees without fruit, twice dead, pulled up by the roots, raging waves of the sea, foaming up their own shame, wandering stars. And listen, I don't know a mega church in our town that doesn't have one of these standing behind their pulpit. Some might say, now, wait a minute. You can't talk about other churches that way. That's harsh. I say we must talk about them that way. Paul here talked about them in that way. Why? Because the stakes are high. If they fail, listen, if they fail, Paul's test of gospel ministry here, then they are leading people to hell. Eternal torment. The stakes could not be any higher. Paul doesn't mince words about this. Turn with me to 2 Corinthians, chapter 11, a few pages to the right. Chapter 11, and look with me at verse 12. Paul doesn't pull punches. And Paul says it plainly, says it clearly. And if you take issue with this, and you don't have issue with me, you've got issue with Paul, right? We're continuing Paul's apostolic ministry here. Chapter 11, look at verse 12. Paul says, but what I do, I will also continue to do. Praise God, Paul, thank you, right? What I do, Paul says, I will also continue to do. Why? That I may cut off the opportunity from those who desire an opportunity to be regarded just as we are in the things of which they boast. You see what Paul's saying there? We have a responsibility to expose the unfruitful works of darkness for the sake of people's souls. Here, Paul says, I'm going to cut off their opportunity as much as I can. And he's going to do that by exposing them. Look at verse 13. For such are false apostles. And the people of the church in Corinth knew exactly who Paul was speaking about. I can make statements from this pulpit, and you know exactly who I'm talking about, right? Paul says, these false apostles are deceitful workers, transforming themselves into apostles of Christ. And no wonder, verse 14, because of who their father is. Satan himself transforms himself into an angel of light. Therefore, it is of no great thing if his ministers also transform themselves into ministers of righteousness, whose end will be according to their works. For them is reserved the blackness of darkness forever. Why? Because souls are at stake. This is heaven and hell, right? He's calling the ministers of Satan, and that's what they are. That's what they are. If Satan wants to have an impact in a church, what is he going to do? He's going to put a minister of his behind the pulpit. For me, last week, multiple issues came up for me with respect to the same church in Orlando. Multiple times this church. This church deceived a precious lady, right, into thinking that she is genuinely converted when she gives absolutely no evidence of a work of grace in her heart. Many of you here have lovingly shared the gospel with her, have poured your heart and soul into her, have prayed for her, have shed tears over her. And she refuses to come here because she's faced with the truth every week that she's not converted. Ultimately, that's what it is. She would rather have her deception. And so she goes to another church and she pulls out a dear brother with her. A dear brother and I were out witnessing this week. We ran into another lady that goes to this same church. She's been going there for years, and she had absolutely no idea what the gospel was. And I have witnessed in this town now four years, and I keep coming across people from the same church, and I have never come across anyone who comes from that church that knows what the gospel is. She's convinced she's going to heaven because of her good works. And listen, folks, that's Christianity 101. Don't be deceived. You're not going to heaven because of your good works. You must put faith alone in Christ alone who has done all the work over the years of preaching the gospel here in Orlando. We've seen one example after another like that from that synagogue of Satan. And that's what it is. It is a synagogue of Satan. Now, you say, well, that's harsh. How can you say that? If you think that's harsh, you don't understand the stakes that are involved. Is it harsh to tell a family who moves into your neighborhood with small children that a pedophile lives down the street? Is that harsh?  What might a Christian brother say who has a loved one in that church deceived by the teaching on their way to hell? What might that Christian brother say? If your mom was there, your sister was there, your brother was there, right? Paul certainly doesn't pull any punches. They're ministers of Satan. Maybe there's someone listening on the radio who has developed some discernment from listening to this by the grace of God. And they avoid going to a place like that. What might they say after the Lord saves them? Praise God, right? From saving me from that error. Paul says in chapter 2 verse 17, for we, Paul says, are not as so many peddling the Word of God. And I like the way the ESV says it. But Paul says, as men of sincerity, as commissioned by God, in the sight of God, we speak in Christ. Paul is distinguishing genuine Christian ministry from all the fake false nonsense that's out there. And he doesn't pull any punches in doing it. Some might object to Paul's statement, right? There are many, the many that you are describing here, Paul, might object to Paul's statement. They also claim to speak for God in Christ. How can we tell the difference? We come back to our question, right? What distinguishes authentic Christian ministry? One fruit of true gospel ministry. Is that fruit discussed in 2 Corinthians chapter 3 verses 1 through 6? It is living letters of the Lord Jesus Christ. Living letters. You want to know what validates gospel ministry. True gospel ministry. It is living letters of the Lord Jesus Christ. You want to know what validates the Word of God as the Word of God preached. It is living letters authored by Christ, written on the heart by the Spirit of God. Living letters of the Lord Jesus Christ. We see that in 2 Corinthians chapter 3 verses 1 through 6. From our text this morning, I want you to see two points, right? Two points that are outlined on your notes. Point one, living letters commend God's workers. Verses 1 through 3. Second point on your notes, living letters commend God's work. In verses 4 through 6. Living letters commend God's workers. God's workers in 1 through 3. Living letters commend God's work in verses 4 through 6. Genuine, God-empowered, new covenant gospel ministry will produce living letters of Christ wrought by the Spirit of God at work in God's people through the preaching of God's Word. That's a mouthful. I want to repeat that. Genuine, true, real. God-empowered, new covenant gospel ministry will inevitably, inexorably produce living letters of the Lord Jesus Christ wrought by the Spirit of God at work in God's people through the preaching of God's Word. That's gospel ministry. That's new covenant ministry. That's how you tell the difference between what is true and what is false. Look at point one on your notes with me. Verses 1 through 3. Living letters commend God's workers. Verse 1, Paul says, do we begin again to commend ourselves? Or do we need, as some others, epistles of commendation to you or letters of commendation from you? You, Paul says, are our epistle written in our hearts, known and read by all men. Clearly, you are an epistle of Christ, ministered by us, written not with ink, but by the Spirit of the living God, not on tablets of stone, but on tablets of flesh, that is, of the heart. Paul finds himself in this letter regularly having to appeal to the Corinthians to essentially trust him over against the false teachers, appealing to the Corinthians that his is the authentic apostolic ministry. And his most recent appeal comes with a statement in chapter 2, verse 17. Look there. Paul says, for we are not, as so many, peddling the Word of God. Paul says, we are men of sincerity. We are commissioned by God. We, Paul says, speak for God. And so in chapter 3, verse 1, then, he asks the question, do we begin again to commend ourselves? It acts like a statement, doesn't it, in chapter 3, verse 1. Here we are commending ourselves again. That's what Paul is essentially saying. The Paul, obviously not alone, in this very difficult ministry in the church at Corinth, although he tends to be the one that sort of draws the most accusational fire, it's apparent from chapter 1, verse 19, that included in that plural we is also Silas and Timothy. Paul, Silas and Timothy have been laboring with this church at Corinth. And so with the three of them in mind, he asks a follow-up question of the church in verse 1. Chapter 3, verse 1, Paul says, or do we need, as some others, epistles of commendation to you or letters of commendation from you? Now, these letters of commendation that Paul is referring to here were very common at that time, very common to send commendation letters. And that's very common throughout church history. I got one last week, right? Very common throughout church history. Essentially, a letter of commendation involves someone vouching for you. Specifically, someone in the church vouching for you. Vouching for your character, right? Vouching for the kind of person you are. Testifying of the fact that you are a genuine brother or a genuine sister in the faith in good standing in the church. That was the purpose of a commendation letter. It was to knit brothers and sisters together in the church, right? A stranger coming from one town, coming into your town. They would come with a letter of commendation, sort of commending you to that fellowship, to that church, knitting brothers and sisters together in the churches. Now, throughout the New Testament, we have several examples of this, okay? Acts 1827, if you want to jot some of these down. Acts 1827 makes reference to a letter of commendation written for Apollos, right? Romans chapter 16, Romans 16.1 begins with a commendation of Phoebe. Paul references a commendation letter. He wrote for John Mark in Colossians chapter 4, verse 10. Why was that important? Because he and John Mark had a falling out on his first missionary journey. And so he writes a letter ahead of John Mark to the church at Colossae, commending John Mark to them, saying, receive that brother. Receive that brother, right? You can see why these letters are so important. Essentially, the entire New Testament letter of Philemon is a commendation letter for Anesimus. Anesimus, this is how churches in that day communicated and protected themselves from wolves who come along dressed in sheep's clothing, right? These letters of commendation, also incidentally, these letters of commendation, a good argument incidentally for church membership. For church membership, they knew who was on the rolls. They didn't know just who was on the rolls. They knew those people, right? They knew them. They had and they shared a good understanding of who was in and who was out, right? Someone who was there in good standing as opposed to someone who wasn't. And despite all the many modern and unwise notions to the contrary, church membership is extremely important for these reasons. We are covenanted together to worship the Lord together, both around our statement of faith and around our practice, our church covenant, if you will, right? We are covenanted together. We know who's in and we know who's out, and that's for good reason. We have a responsibility to admit genuine, born-again, blood-bought Christians to the membership of this church. Here, these commendation letters are for the purposes of communicating that between the churches. Now, the false teachers knew that. False teachers obviously knew that, so they themselves would also travel from church to church with letters of commendation. Their false teacher buddies would write them a letter of commendation that they would walk around with, and they would get into the church that way. There's enough evidence here in our text to suppose that the Judaizers, if you're familiar with them, that the Judaizers would have written these letters of commendation for the false teachers in Corinth. We'll talk about that more as we work through the text. The Judaizers were those who perverted the gospel of grace, right? Perverted the gospel of faith alone and Christ alone by teaching that people must still keep the law to be saved, in addition to faith in Christ. They were wicked false teachers. Paul refers to them, if you look at chapter 3 verse 1, Paul refers to them as some others, right? Some others. Do we need, Paul says, as some others, as these false teachers so to speak, it pistols of commendation to you or letters of commendation from you. And the Greek grammar, if you look at the Greek grammar in chapter 3 verse 1, the grammar helps us to understand this is a rhetorical question. It's a rhetorical question expecting a resounding no answer. Paul is saying, of course we don't, right? Of course we don't need a letter of commendation to you. Of course we don't need letters of commendation from you. Why? Because you know us. You know us. Paul, Silas, Timothy labored among that church for 18 months in planting the church. He's been back now in a couple of visits. He's written multiple letters to them. He gets multiple reports back from them. Paul knows them and they know Paul. Of course we don't. Paul says, look at verse 2, Paul says to the Corinthians, listen, you are our epistle written in our hearts. We don't need a letter from you. You're our letter, Paul says. But literally he says you yourselves are our letter. You can imagine Paul, right? In other words, Paul saying, listen, I preach the gospel to you. I preach the gospel to you. Through that gospel you believed. Paul might have said, I have it labored among you in the Lord. I have shed tears over you. I have prayed with you and prayed for you. That ministry of mine among you has produced fruit. You know what that fruit is? You, you are my fruit.  Paul says, I don't need letters. I have you. I have you. Paul would say to them, Whitney, listen, you are not who you once were. Amen. What a, what a, um, you think about it, right? For that, that's, that's the greatest joy for someone in ministry is you're going to look at the people of God and say, you are not who you once were. And it's because of his own strength, of his own ability, his own wisdom. I'm just so smart.  No, because it is validation. It is clear evidence that the spirit of God is at work through the preaching of God's word to change people's lives. And that is a cause of worship and rejoice and rejoicing. I said the, the, the best validation, the best commendation of gospel ministry. But there are people, they're sitting in this room right now, right? You're sitting across from someone who at one point or another you share the gospel with and they're here worshiping and praising God with you. What a joy, right? What a commendation. Do you need anything else? No Lord, please keep sending them. I want to go share, share the gospel again. I want more letters, so to speak, right? That's a joy. What a validation for Paul. You're not who you once were. And that came, Paul says, through the spirit of God, God working through my ministry among you. What a tremendous commendation. First Corinthians chapter six, nine. First Corinthians chapter six, verse nine.  What a miserable list that is, right? Those are people who are going to hell, Paul says in verse 11. And such were some of you. Praise God, right? The people get saved, the preaching of the gospel. Whether that's preached by me or preached by you, preached by someone else. God works through his word, preach to save his own. What a glorious commendation. Paul says in verse 11 there, you were washed. You were sanctified. You were justified in the name of the Lord Jesus and by the spirit of our God. That didn't happen in exclusion from Paul. Isolated from Paul. That happened through the means of Paul. And it happened through the means of Timothy and it happened through the means of Silas. And it happened through the means of other people in that church at Corinth, right? And it continues to this day, happening through the means of you who preach the gospel. Happens through the means of your efforts, your labor among the people of God. When you pursue a straggling brother, a straggling sister, someone who is isolating themselves or trailing away and you turn them from their sin, it's not you doing that per se. You're just the agent, right? You're the instrumentality through which God does his work. And what a glorious commendation.  Glory, right? That's what tremendous grace that, as Paul testified of himself, the chief of sinners, a proud, insolent, boastful, violent man, persecuting the church, that God would work through his preaching of the everlasting gospel is unfathomable grace, mercy, blessing, love, joy, right? Tremendous, tremendous. Paul asks the direct question in 1 Corinthians chapter 9 verse 1. Paul says, am I not an apostle? Am I not free? Have I not seen Jesus Christ our Lord? Are you, Corinthians, not my work in the Lord? If I am not an apostle to others, yet doubtless, Paul says, I am to you, for you are the seal of my apostleship in the Lord. Paul adds, you are written on my heart, written on our hearts. I'm not carrying around some letter in a bag. You're written on my heart. Can you imagine, right? Maybe you've had that experience of leading someone to the Lord preaching the gospel to them. Maybe you share the gospel with them and they're here. The Lord has saved them. They're worshiping the Lord. What a joy that is, right? What a joy to be a part of a church that does that. Listen, when this church preaches the gospel and you support the preaching of the gospel, when you give to the preaching of the gospel, when you minister to people here, you're a part of that work. That fruit, as Paul says, abounds to your account.   Think about how that person then, the people here, like our work in this church in the gospel, we are not, we are not as so many peddling the word of God here. We don't do that here. We don't peddle the word of God.  People come and they're saved. Consider how that person, those people then, are imprinted on your own heart.  You see their smile. You see their joy. You see them worshiping the Lord. What a joy that is, right? You see that. And that just gets imprinted on your heart. It's not numbers on some denominational role. It's not a list of names on some computer somewhere, X, Y, and Z, this many, this many, this many, that is despicable. These are living letters written on our hearts. That's the church of a living God, right? That's the work of Christ, the work of His Spirit. That's what's here. It's just a blessing about being in this church and that's here. You have people here who genuinely love the Lord. They're reading their Bibles. They're praying. They're worshiping. It's like, it's a blessing. It's a blessing and a joy. You are written on my heart. I pray I'm written on yours. We are in this together, right? It's a joy. Paul says, you're written on our hearts. We love you.  This would have been so, so, so reassuring to Paul. Turn with me to 1 Thessalonians. Let's look at Paul's heart in this. 1 Thessalonians, look at chapter 2, so reassuring, so encouraging, such a cause for rejoicing, hope, right? Knowing that God works all things together for good and He is at work in our midst through the preaching of His Word, preaching of the gospel, what a joy. 1 Thessalonians chapter 2, look at verse 17. Paul says here, but we, brethren, having been taken away from you for a short time in presence, not in heart, we endeavor more eagerly to see your face with great desire. Therefore, we wanted to come to you. You listen to Paul's heart, right? Paul's heart. Even I, Paul, wanted to come to you again and again, but Satan hindered us. Verse 19, for what is our hope? What is our joy, our crown of rejoicing? Is it not even you in the presence of our Lord Jesus Christ that is coming? For you are our glory and our joy. You are our living letter. Paul's joy among many joys in the Christian life, right? Among many joys. But one of those among many is the thought of seeing those Corinthians before Christ. Among the bride, right? At the marriage supper of the lamb, washed without spotter blemish, made perfect, made righteous in his sight, just glorious, right? Glorious. You want to know what distinguishes us from false teachers? In Corinth, Paul asks, you do. You want to know what distinguishes a true church of the Lord Jesus Christ? In Orlando, you do. What distinguishes authentic Christian ministry? Authentic Christians? What distinguishes true from false, true believers? Clear, right? Clear.  You know what I'm talking about? And the stakes are so high, right? The stakes are so high. 2nd Corinthians chapter 3 verse 2, Paul's not referring here to some mere profession of a change of heart, some mere profession alone. That change of heart is obvious to anyone who would consider the Lord's work in these people. It's obvious to anyone. Notice what Paul says further in verse 2.  Known and read by all men. It's obvious. If you're visiting here with us today, I can, because of lengthy experience in this church, pretty much assure you that given opportunity before you make the parking lot, someone's going to share the gospel with you. Now, if you're the type of quote unquote Christian who has difficulty with that, there are a host of problems. And I would submit to you that problem is in your heart. Christians love the gospel. Christians love the word of God. Christians love other Christians. Christians love to preach the gospel. It's known and read by all men. It's obvious when you come here, you're around people who genuinely love the Lord. When I came here, I thought to myself, you know, it may be that in all of my quote unquote Christian experiences, this is the first time I've been around any substantial number of genuine Christians. There's always that one guy, right?  What is it? He's going out with this thing? No, no, no, no, no, no, no, right? And some old, like, curmudgeoning guy. Just give him a little bit of time. He's going to be just like me in another couple of months, right? So genuine Christians love the Bible. They love the word of God. They love serving the Lord. They love serving one another. They love one another. They love long sermons. They love small groups. Show me your faith without your works, said James. You can't do it. Show me your faith without your works. You can't do it. James said, I will show you my faith by my works. You say you believe in God. Fine. Even the demons believe in God and they tremble. The good works that flow from true saving faith distinguish your faith from that of the demons. This is an epistle written in our hearts that is known and read and obvious, overtly obvious to all men. The Corinthians themselves are living letters of commendation for the gospel ministry of Paul, Timothy, and Silas. They are, Paul says, written on our hearts as a living testimony of our work for the Lord. And it's obvious to anyone who sees it. If you're known from your previous life, it's obvious, right? I knew that guy back when and it's not the same guy, not the same guy. My wife and I were unconverted when we were married. The Lord saved me and it was a matter of just a couple of few short months later. My wife is like, you are not the same person I married. Right? And by God's grace and to the everlasting praise of my savior, she was converted and not the same woman that I married just a few months after that. By the grace of God, right? We're not who we once were. No different. This is no different in our day. No different in our day. We tell the difference between the true and the false this way. Apostle Bob. Apostle Bob comes with his letter of commendation from the Charismaniacs. Easy, believism, decisional regeneration. Southern Baptist pastor Dwayne comes with his letter of commendation from a denominational seminary. The Catholic priest has won as does the Seventh Day Adventist, as does the Mormon, as does the Joe as Witness. However, however, the measure of gospel ministry is the overtly obvious Holy Spirit wrought transformation in the lives of God's people. That's what commends true gospel ministry. It's not how many books he's written, right? Not how many sermons he's preached, not how many seminaries he's attended. It's not the certificate from the seminary, right? It's not how popular is that he's not how much he's liked or how nice he is. He may walk around with the Bible. He may even say some biblical sounding things down then. The fruit of genuine gospel ministry is the transformed lives of the people. God says through Jeremiah the prophet, right? God says this, if they, speaking of false teachers, mind you, right? Think about this for a moment. If they had stood in my counsel and had caused my people to hear my words, then they would have turned them from their evil way and from the evil of their doings. If that lousy mouthpiece would have just stood in God's counsel proclaiming God's words to God's people, then he would have turned those people from their sin. Change of life, transformation. And right?  The professing quote unquote evangelical church today looks just like the world. It's a social club in the world. It's crazy. Paul knows all too well. He knows all too well that this is not a work that he himself is capable of bringing about. Paul can't do this in and of himself. Apart from the Lord, he can do nothing. He is simply the means that God has used to bring it about. And he understands that. He continues in 2 Corinthians chapter three, verse three. Look at verse three. Clearly, Paul says, clearly you are an epistle of Christ. It's a living letter of commendation for Paul's ministry, but they are epistles of the Lord Jesus Christ. The Lord Jesus Christ is the author and the finisher of our faith, right? Clearly you are an epistle of Christ. You're not an epistle of some false teacher. You're not an epistle of, listen, you today here, if you're in Christ, listen, I know you. You know me. You're not an epistle of some JW. You're not an epistle of a Mormon. You're not an epistle of a Catholic priest. You're not an epistle of that gospel compromising, easy-believing, easy-believism, pastor down the road. You're not an epistle of that guy. You are an epistle of the Lord Jesus Christ. If you are in him, you bear his marks. You bear evidence of his authorship in your heart. You are an epistle of the Lord Jesus Christ. Ministered by us, Paul says in verse three, right? Delivered by us. Word there is served by us, written not with ink, but by the spirit of the living God. Not on tablets of stone, but on tablets of flesh. That is of the heart. The Paul here glorifies God, right? He doesn't take the glory for himself. He doesn't take credit for himself. He gives credit where credit is due. And he acknowledges here four truths, four truths about genuine gospel ministry. We want to jot these down. One, these living letters are authored by Christ. Two, these living letters are ministered by us. Three, I'm going to repeat them. Just keep writing fast. These living letters are written by the spirit of the living God. And four, these living letters are written on living hearts. One, these living letters are authored by Christ. Two, these living letters are ministered by us. Three, these living letters are written by the spirit of the living God. And four, these living letters are written on living hearts. One, these living living letters are authored by Christ. Clearly Paul says, verse three, you are an epistle of Christ. Jesus Christ, the author and finisher of our faith. Paul knows that the work didn't originate with him. Work didn't originate with Paul. No person can ever take credit for that kind of work, right? He told them in 1 Corinthians chapter 4 verse 16, in Christ Jesus, I have begotten you through the gospel, right? In Christ Jesus, I have begotten you through the gospel. Two, these living letters, Paul says, are ministered by us. Verse three, Diakoneo, these were This is where we get our word deacon from, servant, right? We were servants to this end. We were servants to this end that you are a living letter authored by Christ. He does say, doesn't he? 1 Corinthians chapter 4 verse 16 again, in Christ Jesus, I have begotten you through the gospel, right? Paul is a part of that work. He sees himself as a means or as an agent through which the gospel was preached and through which the Corinthians came to believe, right? He is the Emanuensis, so to speak, the hand by which the spirit of God writes Christ's living letter, right? Paul was the one who preached the gospel to them. That's you, that's me when we preach the gospel, right?  When the word goes out, does not return void? God works through his word. Paul here praises God for that. Verse three, these living letters are written by the spirit of the living God. Paul says, verse three, written not with ink, but by the spirit of the living God. Let's be clear about what this means, right? The spirit of God does not write with invisible ink. You're not a secret Christian. It's not hidden, it's obvious, known and read by all men. The spirit of God doesn't write with invisible ink. The spirit of God does not write with fading or disappearing ink. The spirit of God writes in permanent ink, in neon, flashing, brilliant ink that does not go away. Like, better than one of those Sharpies you can't rinse off, right? The letter is clearly legible for anyone who knows the word of God. It is informative what the spirit of God writes. This is powerful evidence, isn't it? Powerful evidence that the ministry is from God and used by God. You know if you are in Christ that the changes wrought in your heart and in your mind could not have taken place apart from the spirit of the living God.  Not on tablets of stone, Paul says, but on tablets of flesh that is of the heart. Paul says this in 1 Corinthians chapter two verse four. My speech and my preaching, Paul said, were not with persuasive words of human wisdom, but in demonstration of the spirit and of power that your faith should not be in the wisdom of men but in the power of God. Paul knew the power was not in him. This is through the spirit of the living God. I preached, Paul said, the spirit of God was at work, you were saved, you were sanctified, a living letter of Christ was produced, authored by Christ through the agency of the Holy Spirit, a letter that can be known and read by all men. And Paul says, I'm the one who delivered it through the preaching of God's word. He preaches, God gives the increase. The Corinthians themselves then are the living letters commending Paul's ministry. Inarguable proof that God was working through his ministry for the good of the Corinthians. Four, these living letters are written on living hearts. These living letters are written by the spirit of the living God, verse three, not on tablets of stone, but on tablets of flesh, that is, of the heart. We're gonna talk about this more next week with reference to the tablets of stone as we continue to work through our texts and specifically in verse six. Suffice it to say for now that with this statement, Paul is directly challenging false teachers in Corinth. Judaizers were the peddlers, the hucksters of that day, the charlatans and liars who perverted the gospel. The Judaizers insisted on adding Judaistic, external, Judaistic law keeping to the free offer of the gospel and salvation by grace alone through faith alone and Christ alone. They wanted to add works to salvation by grace through faith in Christ. They insisted that circumcision was necessary. In order to be saved, you had to be circumcised. They insisted that the dietary laws be followed, that the calendar be followed, the feast days. And the tablets of stone in verse three that Paul is making reference to here essentially are the two tablets on which was written the Mosaic code, the Ten Commandments, right? In Exodus chapter 31, verse 18, Moses said there that he was given two tablets of the testimony, tablets of stone written with the finger of God. It was the law. These tablets of stone here are referencing the law, the Ten Commandments. What was going on in Corinth was something new. Was something new. Writing those laws on tablets of stone was external. Cold, dead physical stone. But in Corinth and in gospel ministry ever since, God was writing living letters of the Lord Jesus Christ by the agency of the spirit of God engraved internally, not externally on tablets of stone, but internally on tablets of flesh living hearts. Listen to this from the new covenant in Jeremiah chapter 31, verse 33. Listen. God says, but this is the covenant that I will make with the house of Israel after those days says the Lord.  You see? I will be their God, they shall be my people. Same law, right? The law hasn't gone away. It's just that now it's written on hearts of flesh. Do you see? Verse 34, he goes on, no more shall every man teach his neighbor and every man, his brother, saying, know the Lord, for they all shall know me from the least of them to the greatest of them says the Lord, for I will forgive their iniquity and their sin, I will remember no more. The law written by God on those tablets of stone at Sinai was external. It's outside of man, external. Being external, all the law really can do is confront man with his inability to keep it, his utter inability to obey it. And as such, because of that, it condemns men. Law's not bad. The law is holy just and good. But that law externally written on tablets of stone confronts man in his inability, confronts man in his inability to obey. And as such, it condemns man. Bible says cursed is everyone who does not continue in all things which are written in the book of the law to do them. But I'm gonna go to heaven because my good works outweigh my bad works. Cursed is everyone who does not continue in all things which are written in the book of the law to do them. Well, I'm gonna ask forgiveness. God forgives. Cursed is everyone who does not continue in all things which are written in the book of the law to do them. God's law is not abrogated. It's not done away with. God's law stands as a perfect testimony of the character of Almighty God who is perfectly holy and perfectly just. So what does God do? What does God do? In unfathomable grace. In unfathomable mercy. God says, I will write the law on their hearts. Not only on tablets of stone, then they will be able to do them. Ezekiel 36, speaking of the same work of God, listen, Ezekiel 36, God gives his people a new heart. They get a heart transplant, heart of stone taken out of their chest. God gives them a heart of flesh. God in the new covenant places his spirit within them. They are made alive from the dead by divine regenerating grace. So they don't have to keep the law anymore? No. So that those stone tablets could be done away with? No. He says there in verse 27, but so that you will keep my judgments and do them. Right? This work of grace in the heart, this work of writing God's law on the heart is so that God's people can keep it. They can fulfill it. We'll look at that next week. The work of God, the work of God doesn't abrogate his law. It upholds it. It honors it. The work of God enables his people from the heart to keep it, not externally, as if heartlessly following the etchings on a stone tablet, but from the heart in the power of his spirit, in love and joy and hope. Right? This is what Paul is referring to in Corinth. And this has been going on in New Covenant gospel ministry since Pentecost. Right? Have you believed this message? Have you come to understand the free offer of grace in the gospel?    Have you abandoned thinking that somehow or another, it's just all gonna work out? The gospel, genuine salvation, true saving faith is about a work of God done in you, on the tablet of your heart. And that is the validating evidence of the miraculous work of God done through the preaching of his word. You are a living letter if you're in Christ. Paul says, that's the only letter of commendation I need. What is the letter that is written of you? What is the letter that is written of you? You've got one. You've got one. Are you a living letter authored by Christ having been written upon by the spirit of the living God?  Are you pressing on toward being the living letter that commends the work of Christ in you? The work of God's spirit within you. Are you that living letter? Are you a trophy of his grace? Are you a letter that commends the transforming work of God in the gospel of the Lord Jesus Christ? That letter is the joy and crown of our Lord Jesus Christ. Would you trifle with it? That letter is the joy and the crown of those that serve you here. This church is a tremendous encouragement to that end. This church is a constant encouragement in that respect. I know I speak for my brothers. It is a blessing to serve here. Can't imagine being anywhere else. The greatest joy of any gospel minister is to see the godly faithful lives of the people in the church. Are you pressing on toward being that living letter? Maybe that doesn't describe you. Maybe it doesn't describe you. Is your life a letter from Christ commending the work of the spirit of God, giving testimony that you're responding to the preaching of God's word here, or isn't it? If your elders were going to commend the work of God in this church, if your elders were going to, as we do, talk about the grace of God at work in this church, the work of Christ, the glory of God here, would they pick your life as a letter of commendation? If not, what are you going to do about that? What are you going to do about that? What are you going to do to change that? What repentance is necessary? What about your ministry here, brother and sister? What about your ministry here among the people of God? Are you investing in your own crown?   When questioned about the authenticity or the validation of your own ministry, we all have been given that ministry. So if someone were to come along and question your own authenticity, can you point to brothers, sisters, whose lives you have impacted for the gospel? You poured yourself into, poured yourself out for as a drink offering in your service to them because you invested yourself in them, because you ministered to them. If you cannot, then what will you do to change that? This is a glorious truth. The stakes are so high and heaven is near. The end is near. People mock that. The end is near and we have work to do. And the Lord saves. The Lord works through the preaching of his word. That is glorious. All praise, honor and glory to the one who gloriously saves that way. Amen. Let's pray. I want you to spend a few moments and want to ask you to pray silently. And I want you to consider those questions. What kind of letter are you? Do you commend the work of Christ? Do you commend the work of God's spirit or don't you? Would you be picked as a letter of commendation for gospel ministry? If not, why not? What about your ministry here? We need to ask for the Lord's help. We need to ask for the Lord's blessing. We need to ask for conviction. We need to ask for genuine repentance. Let's go before the Lord and pray. When you're done, you are dismissed.


I am Padma and I am from Sri Lanka. I am doing electronic and telecommunication engineering as my undergraduate degree. Currently I have completed my third year. So I am about to go to fourth year which is my final year. And after that I am planning on continuing higher studies. So maybe going to research. So during last year GSOC I joined for CSIA under this pocket science lab project which was a hardware project which was suitable for me as I am doing electronics. So we started from a place and now we are at a very good level ready to go for production. So before starting you may think that this is another ArdinoMega die project or something similar to Raspberry Pi but this is actually quite different from those. The different from ArdinoMega is that ArdinoMega is just a bulk board. It does not come with any software or anything. You have to type a code yourself and upload it and then you set up your circuit using this jumper device and then only it will work. But with pocket science lab the RIS firmware already uploaded into the board. So all you have to do is install the user application, user interface and then just there are controls you can get the result from them directly. So we were developing some prototypes during last year and we have come up with the final design at the moment. So this was the design you can see in front of us and to reduce production cost we have moved all the components to one side. So the manufacturing will be easier and only one step. So this device you may feel like it is very simple but actually offers you a variety of instruments. So one is a 4 channel oscilloscope. A 4 channel oscilloscope is if you buy an industry grade oscilloscope it will cost you around 600 dollars, US dollars and it is very bulky as well and it is not so, a student may cannot be able to afford such a costly device. So we are trying to replace that and trying to remove that barrier using such simple device. So the 4 channel means in case you do not know it can view 4 different waveforms at the same time and you can have a sampling rate up to 2 million samples per second which is quiet reasonable in universities and schools and have an amplitude range from minus 2 plus to 16 volts. So that can actually replace collage oscilloscopes and then it has a voltmeter it also has 6 channels that means you can measure 6 different voltages at the same time and it has a programmer voltage sources that means if you want a certain voltage level for your circuits if you use a battery you get a fixed value. But in this one you can set the range from minus 5 to plus 5 we have 3 different pin sets from the maximum from 5 volt minimum to minus 5 you can have a wide range of voltages with very good accuracy as it is 12 bits and those are the pins relative to it and it also has a current source in many analytical purposes you will need a current source and in normal instruments it is very expensive to use that and also it has logic analysis it also has 4 channels that is for digital circuit analysis basically it supports up to 4 megahertz frequency ranges and it has analog wave generator it can generate a sine wave as well as a triangular waveform frequency is ranging from 10 hertz to 5 kilohertz. So this is quite affordable range for normal circuit analysis and debugging and it also has PWM generator that means digital wave form generator. So in order you know you have to implement the code yourself here we have those pins predefined you for yourself all you have to do is just plug the pin and adjust the control in the application in here and another quite amazing thing is it has capacitance measurement in normal multimeters the capacitance measurement feature is not there it is in quite expensive multimeters. So we have that feature included in our device ranging from picofarad and also it can measure resistance from milli ohm to mega ohm and the another amazing thing is you can connect so many sensors to this device. Sensors which are working on you may not see in I2C an SPI URT protocol like accelerometers, gyroscope, humidity sensors, gas sensors there are so many sensors working on I2C principle because it is I2C you can connect so many pins so many sensors at the same time and read their row value then you can capture the data set and then you can maybe plot to so to analyze so whatever you can do that. It also has a frequency counter it is more similar to logic analyzer and now comes to the open source project this project is hosted on G-Tub in several repositories the first two PSLab Python and PSLab desktop are the source code related to the desktop application and the Android repositories we have Android application as well which you can connect the device to your mobile phone which is Android and PSLab remote is a web server repository for the device and the PSLab firmware report contains the firmware which is written in C++ and the hardware contains all the schematics which is designed in key CAD and all the build off materials if you want to build on yourself you can have all the stuff open there and it was initially it was a very basic device which comes with a two channel oscilloscope and so on and so over the past few years we developed it to this level and the first application was a desktop application and during last year GSOC we developed the Android application and so now we are planning on having the usability to more people by developing coming up with some solutions so this is how the Android application oscilloscope looks like it has all the features a normal classical oscilloscope as and this one is the desktop application so now let me show you some of the stuff you can do with this one okay now this is the so this is the desktop application and it has sold it has access to all the instruments on this step oscilloscope logic analyzer these are for those sensor readings and here we have the sine wave triangle wave generator settings PWM settings so programmable voltage settings here we can measure capacitance and resistance and voltmeter 1 6 channels and the frequency counting also in here we have if we have some frequency settings for wave form generator and PWM so now let me generate a sine wave with a frequency of 500 hertz and then I will show you that from from one channel of our oscilloscope I am opening it and there are four channels here so I have connected one to the third channel some already generating it so we can adjust the time base depending on the frequency of wave waveform you want to have the maximum display on it so you can adjust it here and then you can adjust the resolute amplitude and here we have a knob you can see with that one you can change the amplitude of the generated wave form see we are planning on putting software on up for that one instead of the hardware one and you can do Fourier analysis as well if I go into logic analyzer about the four channels let me first generate a digital pulse that means square wave with only two values here we have here we have on the bottom we have a square wave generating pins just as a skew in the bottom I am choosing two of them they can be arbitrary I am choosing a skew 1 and a skew 2 so that will generate two square pulses and here I am just setting what is the duty cycle duty cycle means in a period of in a in the in one cycle how much how long the pulse will have the logic high level that let me show you that in the wave form let for clearance I will make it 0.6 and then it may open the logic analyzer whenever I have open the logic analyzer in this case I am using two channels the reason is I want to see a phenomenon digital pulses that is they have two different features like falling edge and rising edge these are quite commonly available in processor designing for clocks so let me show you what a rising edge is using this one so we are capturing the data and putting it so there are so many data points so we have to zoom in see here the 60 the 0.6 duty cycle means if we take this length as 1 this length is 0.6 this length is 0.4 that means 60% of the period is 5 volt and you can see the rising edge means transition from logic low to logic high logic low means the there is no voltage logic high means there is the maximum voltage so the rising edge is the transition time so this is the time where the rising edges occurs so you can do many more things like this with this device and to show you how to measure resistance here I have a resistor with 100k it has some tolerance so they and here we have these two pins SCN sensor pin so we are connecting the two edges of the resistor through that pin and when I try to read it it will show you the value correct value because the resistor may say it is 100k but there are tolerance like 5% tolerance in resistors so the actual value can be different if you measure this from an industry grade multimeter it will be the same value and if I try another resistor to verify that term here I have a 560 ohm resistor if I measure it there are also tolerance there was a loose connection that is a you know surround that term now apart from all these instruments we have a special section in our application that is experiments in a school or a university you have to give the student a practical experience they have in the curriculum they have different different experiment teacher will give you a lab sheet and the schematics to make with all the components and the student have to make the circuit and get different readings and draw some plots so we have a similar approach in our application so let me show you how a diode bill looks like if we have the instruction to connect how it is so the schematic is not shown here here you can change the input and out input parameters here it will have different curves so different likewise we have a whole set of experiments in different different categories electronic experiments are basically for high school and university level students because they are as you can see they are a bit complicated op-amps ramp generators so for school level students we have simple application like measuring voltage and how to make a lemon cell and what is ohm's low and so on so that's all about our application in a nutshell so and also we can design experiments rather than just having the experiments designed by that by us you can design them yourself by selecting which are the components you need and what are the readings you want to get in what range and then you can have a simple view and with this one you can just gather some data by connecting meaningful circuit and then you can plot them now it's just open so it's all this graph may be not meaningful but if you have a design on your mind you can have the design in this application okay so what do you guys think so it struck me that it would make a very good test bench platform for a lot of projects yes it's not just science and actually when I look at this I'm thinking more like if I'm building a hardware and I want to automate the testing of the electronic this would be very useful and actually measure point points and free expected value range and connect that and have signals as they input to that device and measure the outputs yeah that's that so to me more like I don't I know understand that scientific aspect in the name but to me this is this sounds more like a great tool to test other electronic and apart from having the this GUI here we have this application was written in python so we have a library yeah import it and then you can have here here we have some sample functions here the capture one is a function called to get the voltage reading from channel one so if you are if you want to let's say you are having some application where you want to just automate this thing so you can have a python script running and getting data and you can process it so what's the communication between the platform right now it's you what it's what you are it's a it's a serial serial communication and I think you can discuss like bluetooth at some point bluetooth and wi-fi bluetooth or wi-fi as the as a thing yeah to make it wireless wireless okay so actually the current hardware can be extended with an ESP yeah yes so at the bottom side of the hardware there is an open socket for you can solder an ESP yeah and make it wireless yes and at the bottom there is a when you can program it yourself down there ESP you can have a web server uploaded to the firmware and then have the UR communication same as the USB cable so that way you'll you'll only have to power up the device device and the ESP and then you don't need the USB connection with computer anymore you can have it as an access point connect the computer to that turn then have the application running easily what else can you extend here we have a NRF module as well it's kind of similar to how an ESP works and if you want to tinker with the firmware here we have the programmer pin set it's an ICSP programmer yep so can you talk a bit about like using external sensors yes so we have the i2c connector in the top with that as i2c is made to connect so many devices using only four wires so we can connect plenty of devices like accelerometers gas sensors mm barometric pressure sensors light sensors there are so many sensors available in the market they're all compatible so you can connect any amount of sensors and then get their row values then you can export them as csv format with that you can either use matlab or whatever the tool you prefer and you can process that data what are the functions of the functions of what are the functions of your computer what can you measure what meter what meter a voltmeter a voltmeter a voltmeter can measure six different voltages at the same time they have also resistance and capacitance and also current it can measure voltages up to minus 16 to plus 16 that's the no not ac it can be dco ac as long as the range is between minus 16 to plus 16 a bowl so good we cannot measure bowl so good ac is not good how you measure ac bowl so good we cannot measure bowl so good we cannot measure bowl so good no no i'm saying they say i'm only have a five volt ac how do you measure ac here we have a capacitor connected across this ac one pin it's a it's the same pin as channel one we have a 10 micro farad capacitor connected across ch1 and ac1 with that one we can input a ac wave so let me show you the average value yeah rms now for your logic analyzer your four mega hertz is per channel yeah here for your scope do you have filtering inside input and output uh filtering or just the waveform coming out yeah directly and it will amplify according to the setting we choose it see it's between 16 or plus 16 or minus 16 or plus five to minus five for the amplitude resolution range it will show the gain what kind of power does it require can i make it stand alone and leave it in the garden time yes it's a how would i keep the data and then collect it at a later time for that you will have to use an esp yes without an esp you need a wired connection with esp you may need you may can have it as an access point connect some mobile phone or laptop to that and have the application fetch it every maybe some interval and you can get the data is there possibility we can connect to an sd card for instance i know everything can make that happen collect data i mean sometimes we want to leave it out in the form or something like that yeah that's a good suggestion like we have to decide what is most useful for people so it's very good that you give this feedback that would be useful for you but it's not just the sd card you're actually able to run a server if you want to collect the data locally right now we just plug in a usb either to the laptop or to the mobile phone because we say already the mobile phone has a screen the mobile phone already has all this processing power and so we we are collecting the data so theoretically you could also just take a cheap mobile phone connect it to the box well mobile phones now old ones for 46 so what's the minimum requirement let's say when connect the i think marsh mellow sir oba will support otg because to connect to a mobile phone we need a special cable otg cable so other samsung devices doesn't support otg that's the problem but it seems to me like that what you suggested the path of like having it more or less and a computer is as a web interface is much better right because like yes full screen like you have a lot more possibilities to do that than with their mobile phone like i feel the interface on the mobile phone is very limiting in terms of it's more built out of it right like i i because if you look at the higher range oscilloscope what they have is like a bigger screen and more but then so then you're placed up by a computer it's better yes to see this whole path of like the embedded phones depends the use case so we have we're supporting both use cases yeah educational and like let's say scientific and startup yeah hardware creators so actually like so for educational area and we were looking like at android as like in many emerging countries on the android phone yeah and of course like in like in singapore or windows so and for the desktop you also need to install a server you need to run a server on the desktop so it's not just a desktop app that you quickly install at the moment there are options to go that way but also we have to look at our resources so it's not just do we do this or that it's just the question what do we do first right so so android app seems to be like supporting already a lot of devices and the idea would then be that we now the next few months connect like we add connections like let's say you could collect data and for example send it to a spreadsheet collected csp but also send live like let's say to google docs a spreadsheet that you can share with different people it's not entirely open source but like in future we will have of course collaboration office and so right it's just the question like what what do we do first and yeah but i think i i find really interesting so we've just been to it west with brilliant tan and he also said well this is very exciting with the sensors because i like the idea of the star trek probe yeah like we are arriving at a new planet and okay we have a choice of about 1000 sensors but some sensors we don't need for this planet let's let's put like 200 sensors inside and send the probe to the planet yeah water atmosphere what gas it is and so on so actually with the breadboard we can already like attach ten tens or dozens of devices right now right so there is like so you can like if you don't use the breadboard you can attach one in the next version we will extend this we have four more pins actually because we have space we realize we have space and but like already now if you use a breadboard you can attach a lot of devices so it's very good for prototyping or for like some signs so you could like put them in a box put it somewhere and show it to a customer and say this is our prototype whereas with adrino recipe they have like to build everything up with the firmware you know fiddle around and here you get the data straight away and you could just like say it's my prototype i'm collecting data but you have an icc support right yeah so you could use a bus with a single just two three wires you don't need you don't need additional pins you can just base and change the sense you mean with these four pins yeah you could do icc yes so what the thing is so breadboards can be shaky so we can have some additional connection on the body itself because we have just some space here so we can spare that to the socket like this one i missed your explanation is there another expansion there marked nrf24 yeah for wireless wireless yeah so there's two wireless there's two wireless solutions yeah you can and the firmware is already there in the chip nice the only thing needed is the hardware because oh so it's just the standalone i mean unwired approach yeah only we need to power up the device it has a supply regulator i could connect a normal battery yeah yeah this chip is using 3.3 it's all regulated here what's the maximum the 12 volt battery yeah so one thing that we discussed in the last two weeks for example was having like a charger battery and like a solar panel yeah i mean the question is what do we include with the device right you don't need that but you could use that and then just pull it out somewhere yeah which can actually connect the small display so so somehow you don't need like a computer to actually see what's the battery going on you can actually like operate as a less than two devices i mean about a meter or a meter yeah so so i don't know so i don't know their question we could like go different ways now for example like if you're interested like what's our roadmap and how are we planning to produce it and so we could talk about this or we could also like sit down here people are interested on the table because i saw somewhere like standing up when Fatma was doing something so we could like more go into detail and do like a few experiments so generally like Roland Turner and can't be here tonight but he will he's planning to make more workshops over the next few months also until make a fear so we haven't really done workshops yet it's like for us is right like still figuring it out and so we're getting tonight the OTG cable or adapter we have like one or two there only now so you can already now connect it to the to the laptop right but the beauty of android coming back there is like you download the app from the app store and you're ready to go whereas with the laptop it's a procedure to install it right it's not just like click and go so yeah these options or do you have anything else Fatma I think that's about it yeah so what we're doing like this is also Google some of code project over the next few months so if you have any feature requests we're happy to take them in and so we are focusing on the android app but also on a progressive web app which is like Sebastian Dekas gave some ideas here because we weren't sure how's the data processed yeah you wanted like you don't want to send it to a server and then it comes back and there's a delay or something like that so so he gave us some ideas how to progress here so you can process everything and so there are some questions for example with iOS and it's not supporting like it's not very open we learned yesterday more details so so right now it's it's right now very open it's not supporting the usb support or bluetooth and it's very private to them oh because you need to get the device for supply yeah yeah so so we can only like plug in what they allow some advice is there is that you are because so you guys push everything to serial right you have a message format specified message format is that pretty well documented in terms of like I think all our documentation is pretty good but of course you will find things that are okay but like usually we we document a lot there are also a lot of posts on our blog and every repository has like a read me and all the details okay yeah but where would I find the serial protocol documentation let's say I want to connect my Mac to it and start sending messages and risk messages and collecting the data to influx tv and do something like that yeah is that in firmware that's that's seen firmware truly it's not that much documented how the hardware communication I see it on the website there's a python library is that a python library yeah I could just get that yeah essentially it's like a character base right in the kitchen what for the I triple format instrument communication the standard format that putting point and so on then what was the name of that format I I do see I do see that's a sensor I know I don't know a serial documentation format the serious measurement equipment see the local standard yeah documentation format no when you send to your UART to your yes left yeah what is what is the protocol usually there is a standard for instrumentation in the I triple format um we are we have a set of our own commands it's like we have first categorized yeah categorized what are the documentation we use for us yes that's a good I mean I so there's science lab the p y right science lab the p y is the thing important python from the desktop and yeah it has uh it has the python definition for the communication in there so for some of the libraries actually they just derivatives from xpeg eyes so we didn't start that started from scratch right it's a very good question because of course we want to stick to standards right so I give you some some examples yeah yeah but I I don't like there are some Python libraries so I would say probably they stick to standards are you listening yeah can you help us yeah check that out you always need new people to get in yeah so right now so the production right now is around like 110 a bit about about between 110 120 um $6 but like it will like we produced a 50 in this batch so not so many we'll go down and yeah so we are still like checking because it's hardware we are a bit afraid to produce a lot so but like so so target would be something around 30 dollars maybe if we can get their production cost and so that would be cool but like if we add like SD card or something we can't keep it so so so our thing is like we always want to add something also but we want to keep the cost so it's like a constant fight with night what we do it's always a possibility to show a tutorial how to add exactly to connect to an SD card if like the additional like yeah probably you can have a footprint for a generic uh folder SD folder so like people just call to the other side yeah yeah exactly so yeah it's good to get the feedback and yeah that's that's it so this pocket time so the we gave like two boxes around so one box was also with the like we we had what's it an English amplifier gain to control the gain yeah but actually we just thought like we could do that digitally so we we take it out one one less button yeah and um we'll see other one there oh okay yeah so that one we just made in the Kiwi's office like three days ago so it's slightly smaller and by the way they are compatible with the Arduino so so if you see that here we find you will see like the below the sticker there are some holes from Arduino but like our box will our own box will not be entirely compatible because we will not if it's Arduino they will have more space here they will have it longer we don't have that long space and also we want to keep only the inside screws we don't want to have a bigger box so we want to make it as small as possible but the pocket is small as possible so that's what we do but anyways you could you could take an Arduino box yeah if you if you want and you can produce the whole thing yourself so the whole schematics are online with the key and yeah so you can just download it and try it out yeah and so we have different versions yes because like they're really different like we have version one two three four because they're really different like previous versions didn't have a clue about production so we thought let's make it really small that we put all the components on two sides actually it increased the cost a lot so we lowered the cost by a quarter by putting everything on one side these are the previous version this one is the first one it has uh it has all the components on both sides this one with side modifications can we use the Raspberry Pi with it? what? Raspberry Pi with it yeah well yeah you can use it in events of what you want to do you can use the Raspberry Pi just how we use the computer now yeah so yeah so so this is our staff version we really want to make this successful so we're thinking about how to do the kick set how to do a kick set a campaign and so on yeah you would buy it? I would for the last two years I've been sporadically giving lessons to secondary school children on the microbin so it's a different space altogether the microbin for introduction but they are already connecting to a variety of sensors and actuators this is targeted for a different space of people right so um it has to have a little more than the microbin and the microbin is already got things that I asked for earlier like wireless connectivity easy programming and stuff like that so I think there might be some room for improvement before you put it out kick start yeah so one thing that we said is like you save a lot of time so you can connect your sensors for example very quickly yeah and get data so with micro that you have to program it first so but like and program it but it can be made into a standalone project you leave it out in the garden having microbin talk to another in a mesh form or hopping form right they can get data of their garden water plants and stuff information about it right so I was hoping that this could do something similar or even more more than what I could do with microbin so that's why I asked maybe there are some things that we can improve and microbin is a pretty relevant piece of device given to secondary school students today so I think I would like this to be more successful than the premium it's a premium option yes yeah what what do others want if you have the clearly documented protocol yes I can even use the microbin to take your time control it guys yeah I think the microbin could see your communication yeah I mean I think I think if we can write like because it's already a Python library right so just just going that way I think it's more software right it's on the software side like developing the features so that it integrates with the existing hardware we've heard the rest pie like a pc like other platforms it's all about like people want it on their platform but you're not going to be building all of that we need to get people to maintain these this support for their argument so I think it's that direction that's pretty good but I think you know because you think you can build it for a lot of different people but I think you already have a good sense of what kind of application you want to do right which is measurement and and kind of tasks and kind of these things so what what scenarios can you cover like thinking more about that I think this is hot so this is our first thing and our next thing is this big sign so one sensor that we want to get connect is our friend's new new box yeah I've got one so here are different pieces this is also hardware it's like a bit um so it's like a to to measure brain waves so we are looking if we instead of having this thing that they made kind of a little acotic way if we can support for example with this lab it sounds like as well so because the the great thing what they did is they really um have medical great accuracy accuracy so there are like some devices also in Singapore and elsewhere they're relatively cheap um but like they don't get such a quality of brain waves so here with a few sensors we get very high accuracy there's this amazing Japanese guy who's just an into it for 30 years see the guy will always wear that year no it's not him it's another guy who's also very much into aliens and yeah but like yeah it's cool so yeah this this one one where we could go for example so we want basically it's not just about building one device we want a team we want people who work together and we want to push this idea of open source hardware out there as well so um like if other people could use it we also win and we'll contribute back to the project they would say isn't that so that's that's our idea so basically if you have this idea it's also online yeah so um yeah yeah good so now it is what's the time 8 10 yeah so I don't know if you if you want we could like uh have partner maybe you could show us a few more things how you actually connect that and if people want to know sit actually around the table also we could do that yeah oh if you have another suggestion yes oh yeah so for the the android and the desktop versions is the functionality the same yes or is there a function only a desktop no both the functionalities are in both applications but uh for now the maybe the approach will be a bit different maybe we don't have all of it in the android app yet yeah but over the summer yeah we have completed because we we have now with the sum of code we have five people who work on it so okay students look like you know but still they have a clear plan so everything will be supported in the next two months and you can already like the current app is already on the app store so um it's still in testing but you can find it already so how do you see the collaboration with like your because in china's we have you have a couple manufacturer of open source hardware uh df robot c studio things like that and I think you guys have an approach them yeah right no no we produce it in uh with six million miles of studio okay already yeah so they are they are relatively expensive but for me so um yeah we're checking out others as well for larger quantities so the the idea would be to have the Kickstarter at the end of the summer so to say in the end like ready for christmas you're open and I don't know like we haven't figured out how much like what makes sense because usually rather conservative so if anyone has feedback about this project here what do you think do you have feedback yeah i'm just thinking i'm just thinking how because i know a couple electronic uh like in manufacturers in in in shanghai right they're pretty good for like shan shan shan is very good for large quantities but shanghai actually for smaller quantities uh batches it's good yeah i have a contact for the product i said the good guy so i think he's quite low cost but he doesn't do testing but he assembles a lot of them yeah so um yes i think it would be pretty pretty good to have like a automated testing procedure shield type of thing because if you're moving to production that should be one of your side projects actually having having some sort of of test harness you can put on the board because so once it goes production comes out especially in china like you get a lot of defect so you want to make sure you have a systematic way to solve the features um and that like if you put one of this i think put one of the student on that would be a good investment just test harness if you have someone that does hardware and software right and at the same time it's i mean it shows off the feature of the the hardware because you have like it's a oscilloscope and a signal generator and i like i saw it a little bit at the beginning the presentation right you generate the sine wave and you measure the sine wave on the same device so that's kind of testing you can make you should make systematic and then have software to check that you know the whole hardware is working correctly because once you move to production with 10 000 units how are you going to test it you can just ship it it's super important of that of a project like that thanks for signing up as a mentor yeah yes definitely so we have to test because we have software testing but i think hardware testing we don't have it yet right just everything yeah so i did travels and yeah makes a big difference yes so any any feature requested to that let's verify what let's verify let's verify so connect it like every tutorial something everything like just to connect we're used together we're satisfied sometimes yeah but that shouldn't be too hard i think it's the documentation problem right it's just someone sitting down and plugging because the hardware is already all there so it's not that it would be very challenging but again i think it's a it's probably more documentation right like showing off all the facilities having some sort manual what you're saying is that you're targeting people who already have a background in titan you know no no no why no documentation is documentation right so it's also for the feature of this thing and like the like i saw a little bit like they have some framework to create experiments but i think if you're going to do this with kids like they need like the whole step like walk through you know it's it because you're actually the the target here is teachers right like you you said showing it to kids you get this piece of hardware teachers are always like okay what do i do now right like what what kind of things can i do with this thing so you need to give them the experiment you need to like you have the potato let's measure voltage on the potato when the lemon and like some other things right then things like that that's what they want you know there's a good opportunity here yeah this year is the first year in Singapore where all levels have a computing subject and it's done in titan okay yeah so maybe you can have a tie up with schools or yeah so they start off at secondary three so last year they started secondary three those students in secondary three this year is doing their all levels yeah that's that kind of stuff it's all going to be down to content i think the hardware all the features stuff like that like it's fine it's good it's great but now it's all about what you've documented as experiments that kids can complete right live by teachers so yeah that's why we're just at it and yeah so we have two nutrients at it you work on this we're doing doing experiments documentation that's very good just like that so so they focus on sensors they don't focus on python this project so they they just connect one sensor and like okay first you take this wire and you plug it in there and yeah so they have a lot of different sensors already they have everything there and they can just like go through and do it so i hope yeah it seems like the william tan he's really pushing for it so it seems like so and then we work together with dunman high school this was asia projects anyways but i'm not yet clear if they do python what specifically what they do i think like usually they have like some some project that's already like really made projects like macro bit or something so so i'm not exactly clear what specifically what they make i mean i think that if we if you could give us like a question and that we can and then we can follow the question so what we did just last week was also we wrote down a lot of questions yeah because pat mar just comes and shows the devices it's great there can be many things then like uh like people like you right they say oh yeah i can see it and totally see it but like a lot of people say well i'm interested in the subject but i don't know no what what does it mean many things what so many things yeah i saw help in some way is the measurement aspect yeah i see this is full of features but certain terms and measurements we have to be clear yeah so obviously your boat meter only can do this you cannot combine your answer you give me it's not really so we just have to be clear in it documenting the aspect yeah okay and i can give you some advice yeah that would be oscilloscope oscilloscope is measure ac but through ac boat meter is different so those are things yeah so your oscilloscope is to make us a perfect second so your what is the bandwidth of your so for professional it's like there's some information yeah some major information on the measurements i need to be clear yeah yeah so how how do how would one do that how would one go ahead with that so basically write down what we have or put together what we have and then so so for example like yeah well is that your target is that your target market like professionals like every professional you when you're talking to school uh you you have to be quite clear in certain aspect when you start talking about management if there's a difference between data and measuring so if you if you study some data then it's fine yeah you are there but so so what i think they need is textbooks like they need the textbooks and they need the teacher's guide that's what no i'm not even there i'm just saying when you when you put this up like what do you know website we just have to clarify what the measurement part of it and look that that is not a lot of work just just to give you some feedback still my my my question would be how much would put that work in a professional where really there are startups who say oh cool i can use that to measure some things in my hardware i don't need these devices and a partner said earlier that it's like people devices could like add up already whereas here we have one but like i don't know myself enough to to say oh it's good enough or you know or something to say my my opinion many years in measurement field it's not up to professional yet this is almost a DIY but if you really want to go further then we have to look into the methodology the calibration of course those of spending we can get some current specification and will be i think it's useful for some lower frequency use but we just have to clarify the specification because they are on seats to you there are devices that cover some of what we cover but they they marketed it something very professional well thank you very much yeah awesome okay thank you


Three reasons why the narcissist is still watching you.  It's made you paranoid It's made you always check your surroundings Because you never know if they're lurking in the shadows At some point you figured out that they were watching you Or maybe they left you a clue Something for you to ruminate over Because narcissists love it when you're constantly thinking about them Wondering why they said or did something Maybe they liked or commented on a social media post through a different account Maybe they called you from a different number Maybe you caught them lurking around your house or workplace They have their way of letting you know that they're still there You can't get rid of them that easily And there are three main reasons why they're doing that One, narcissistic supply One of the main reasons why the narcissist is still watching you Is for narcissistic supply After everything they've done to you They want to know if you're still hurting They want to know if you're still going through it They always return to the scene of the crime Just to witness the damage they've caused It makes them feel powerful and significant To know that they have altered the natural course and progression of your life It allows them to elevate themselves at your expense One of the main reasons why they're still watching you Is because they want to see if you're still suffering They want to see if you've managed to overcome everything they did to you They're not watching you because they care They're not watching you because they want to help you It's the result of their sadistic nature They can't just leave you alone because they get a kick out of it It gives them an adrenaline rush to see you struggling It's like they're watching a movie They're just sitting back and enjoying the show It fulfills them It makes them feel better about their own lives But if you have managed to turn your life around It's going to make them sick They don't want to see that They're only checking back in because they want to see you struggling They want to see you down and out That's what they're looking for Because that makes them feel better about themselves Which is why you need to stay strong You need to rebuild everything that they tried to destroy Don't give them the satisfaction Show them that they haven't defeated you Show them that you're still able to do what you need to do You're still able to live the life that you want to live To sabotage The narcissist is still watching you To see if you're still suffering If you're not suffering They will try to sabotage whatever it is that's making you happy Because they look at it like it's a hindrance to their progress It's an obstacle to what they're trying to accomplish So if there's anything that you're working on They will try to tear it apart Because it shines the light on everything that is wrong with them It makes them feel bad about their lives So they have to destroy it They will try to turn people against you They will harass you They will steal from you Misery loves company They will do anything to make you miserable just like them 3. Hoovering Another reason why the narcissist is still watching you Is because they're planning to hoover you But they need to determine when is the right time for them to come back They want to come back at a time where you are most likely to accept them back At a time where you are at a vulnerable point in your life Maybe you've had an argument with someone Or maybe you're struggling financially That's when they're going to come back to play the hero To act like they're there to save the day When really, they're just coming back to cause more problems for you If you left them, they're only going to come back to punish you So please do not fall for their hoover attempts They have nothing to bring to you but abuse and manipulation They're watching you because they're plotting to take something from you Narcissists only have their eyes on things that they are envious or jealous of Things that they want to take Or things that they believe are being taken away from them They're not watching you because they want to share anything to you They're only looking at what they can get The narcissist will still be watching you So please take the appropriate measures to protect yourselves Lock your doors Close your blinds Especially at night Keep your social media profiles on private And be cautious when talking to strangers You never know if it's one of the narcissist's flying monkeys Just stay safe out there Narcissists are dangerous people You never know what they're going to do next You never know what they're capable of But just know that they may still be watching you somewhere behind the scenes Thank you for watching I hope this video resonates with you Please like, comment Share and subscribe If you would like to donate My PayPal link is in the video description Coaching inquiries You can email me at coaching at NarcSurviver.uk Thank you for watching And I'll talk to you soon


Yes, Tim Curry was funny. He wasn't scary That series never scared me all I remember about it being is that it was boring and Dragged like Sometimes King can do first thing I will say this movie has some of the best editing of this year by far The amount of content the amount of character development the amount of backstory the amount of confrontations and the amount of actual dialogue and story progression is Amazing when you consider that this is all put within two hours Literally on the mark of almost two hours I could not believe it but I had to actually check and see how much time it passed Considering how much it happened yet. It is flowed so well the child actors in this movie are amazing Every one of them is fantastic unique and has a great Addition to the story whether it be their humor their character development and how they deal with it or Pennywise Finn Wolf guard or whatever his name is from Stranger Things.  He's got some of the funniest dialogue in this movie. Oh, here's another thing too This movie's rated R. I didn't know that until literally going in. I just didn't really look much into it I didn't think it was gonna fail at it's now. There was gonna be average But however within the first five minutes, you will see that this is an R rated movie Mainly with what happens with Georgie. Holy shit Georgie Bill Skosgard as Pennywise is fantastic He has great humor, but he also is absolutely terrifying the means of which how he uses fear to affect the kids is Fantastic the dialogue of this film is on point whether it be with the characters Progressing or with a humor the humor spot fucking on this film does have Carrie Fukunawa I believe his name is he was the director of the first season of true detective He's a writer on this show and you can see his work in this film One thing I also will point out is how good the cinematography is does a lot of this kind of tilting business Which is seen a lot in Korean or Japanese horror movies and they use it really really well in this film All in all the only things that I would say that might be a little bit effective is there is a lot of content You are lost at some points There is a reference to certain people who have gone missing that show up for a scare later on But the problem is you kind of mix them up with other people who have died There are a few deaths that should affect the characters more if not Side characters, but you don't seem to see any sort of effect on them. They don't even react really Then of course, this is a Stephen King's trope, but the bully in this movie is a psychopath He is an absolute insane person like they push it way Too much in my opinion, but it does work for what the film is It's just it's so ridiculous seeing this stupid bully stereotype over and over again But in the end it is one of the best movies of the year and not only is a great movie to watch It not only has a great cast, but it is genuinely scary not just with the scares, but with just the atmosphere I was so intrigued as to what I would see next I didn't even care that I had a bunch of drunk douchebags on their phones and Chatting in front of me because I was so into it and admittedly every time a scare scene was coming everyone in the theater would stop talking which is You know a pretty good thing considering this day and age So my final rating for it is a six out of seven. This is a near perfect movie. It is a Amazing time. It is a great scare And it's just a really good movie Stephen King is probably happy that he's finally got a really good movie Based on his horror work. He's had such great luck with his dramas and his life stories But he's never had anything besides the mist and a few other things have always been me like good or mediocre But this is exceptional you guys should definitely go out and see it. Anyways guys, that's all for me I hope you enjoyed this review. See you guys next time
