All right, any questions? We do an exam Friday, open book, open notes. We'll be over, I think, the first three chapters, which takes us, no, first two chapters is off. So we've got the rectilinear motion, curvilinear motion, couple of coordinates. Won't be a big deal. Now, in any of those, I'm not trying to trick you on any of this stuff. Just see if we got the basics well enough to keep moving. Because we do accumulate a lot of what we're getting here. Have a couple choices of what we can do today. Got another constrained motion problem. I also have some of the problems from last year's exam. So we can look at any one of those you want. What? What was the name of last year's exam? Last year's exam. Okay. You may have lost, I had a dream about you. Right. It was in physics class, so it was exam day, you started taking an exam, and then you started talking to someone. But you took your exam away, and then you started crying, because you said the reason you were talking was because somebody died, you just got a text message. I decided, well, do it. He's getting text messages here in an exam. Should I let that go? Or, so, ended up just taking the test away for 10 minutes, cried for a while, and I woke up. So this is the paper. This is what? One of the homework questions? Yeah. Was it? Okay. Well, that probably got us in from the same place. So, we don't need that one. That's just a rectilinear motion on one, deep, and only go up or down. So you need to assume constant accelerations for other things. This one was, well, it was an illustration, kind of an illustration, to show that different coordinate systems can be used on the very same problem. Because with the northeast coordinate system, some of the students chose to do X, Y, I, J notation. Some others went ahead and put in the normal tangential coordinate system and answered it in that way. And I accepted either one, because I didn't make a specification of how it should be. Well, that one should look pretty straightforward, is it? Like, coordinates, coordinates to use. All right? What? All right. No. My question is super. That's fine. That's okay, because that's what I just said. This one was to illustrate that on some problems, either one can use. That's how it can work. In fact, even the polar coordinates would work on this one as well. So on this one, you were given a car traveling in a circular radius path at a certain point, at a speed of 45 miles per hour, 30 degrees north of east. Didn't actually label it, but I guess I expected the students to come up with that, was 30 degrees. And it's speed is increasing in a rate of five feet per second. You were to determine the acceleration. Remember, acceleration is a vector, so I needed some representation that would give me a full vector solution for this. I also said I wanted it to be feet per second squared. Okay? Let's tell you to read it. 450 foot radius on that term. For a car, actually, it's a fairly tight term. Now, this is one I think would be easier in normal tangential coordinates. Why is that? Because Alex asked that very thing, he said that I'm sometimes confused in which coordinate systems I should use. Well, I'm very good. Kind of the normal tangential. We have the normal component that's directed right towards the center and the tangential. Oh, wait, we used E. Some books use just the N and the D. Subscript C for C triple or C triple, or C triple. On that, I'd rather have the normal because it is the normal component. It's not a centripetal component. All right, I suppose you'd have to read it. Actually, yeah, now that you bring it up, I think our book uses the, yeah, I know they use a normal, but I think they had the normal component. No, they do have it to the inside of the circle. All right, so then the question remains and to help Alex with this, why would this be easier to do it than normal tangential components for this problem? Right, another question here? Yeah. Yeah, Jay? So do you have the tangential acceleration? We already have the tangential acceleration. In fact, remember this acceleration is made up of a piece in each of the two directions. And from the wording, this speed is increasing at five feet per second. That is the tangential acceleration. But not only that, what else is true? The normal acceleration is the centripetal acceleration, which is why Jake asked, can I call it that? And we know that the D squared are actually for this we call it D squared over row, but it's the same thing. And I would certainly wouldn't comment off for that.  Jeopardy is gonna have a computer, is one of the contestants, an IBM computer. They've been working, I think, five years. Got through hundreds of test matches and now they're, tonight for three nights, the computer goes up against the two biggest Jeopardy champions ever. And on cash cab debuts in Chicago tonight, cash cab Chicago, one of the people getting on is a friend of mine from elementary and junior high school. Yeah, yeah, so I'm famous tonight. So extra credit for watching both and then writing more important. So the computer, Jeopardy's going home three nights. Three nights this week, so that'll be pretty interesting. All right, so what deals remain? What VDU's, since it's accelerated? Yeah, even though the velocity's changing, it's the acceleration, it's the velocity at that instant shown gives you an acceleration at that instant shown. So if you choose to just do it in the normal tangential components, I think the hardest thing left is you gotta make sure the 45 miles per hour is in feet per second. That's about the hardest part of the whole thing, was for normal tangential components, we tend to use for the radius of the curvature at that point. That could change as well as could the center of the curvature because very few curves are actually truly circular for more than a little bit. What? I mean, is it hard? Yeah. Do you like seeing that? Now you've got columns, not a missile disease. Spreading. That would go back to what you wish. Is someone saying that's not spreading? No, no, no. Is someone saying that's not spreading? Is someone? Yeah. Yeah, I'm happy to do it if you'd like, but. Happy to do it if you're stumped and homework's due Friday and so probably sometime Thursday I'll post the solutions. Perfect homework support this week. Remember, I'm not great at the content. I'm great at the performance. See if you do a good job putting them together and then you check and see if you're doing it right. Oh, why don't homework you wanna look at or other than these? What are you guys and gal that you need? Are we gonna have one that we have to use more than this? No. It. There may be one where I would hope you would. Remember, the ones that are good for that are the cases where the center point is fixed and so you have, especially some kind of tracking satellites type thing where the information from the satellite would be exactly the things you need for the pull up ordinance and it would be just a matter of filling it in and you have R, R dot and R double dot. That's very easy data. In fact, most of you I think have used those, those TI calculator physics things, CVLs I think they're called. Calculator based laboratory things. You might have used those in high school. We've got a full set of them. We just can't figure out how to use them. It gives exactly that kind of stuff and then also theta, theta dot and theta double dot and once you have any of those, it's a matter of just plugging them into the polar coordinate equations. I just know some of that homework is like really like there's a lot of substituting like the variables and the gauss and the gauss. Well, that's okay because we'd find you. We'd track you on radar. Okay. We'd just take a swell and fill in the equations come get you. So, let's take your little pup, Tim. Where do I get you? Simple as that, that one's pretty straight forward. No tricks I don't think. Like I said, the hardest thing is just getting that into the, you've already been given that. I think getting the end of the beat per second. So, just a matter of putting it in, multiplying it, keeping it new and straight. What students were allowed to do if they wanted to, though I can't imagine why they'd want to, is they were certainly allowed to put it into X and Y for it. Certainly allowed to, and it's not wrong if you do so, it's just remember every time you take a step like this when you go from one place to another place, it's a chance for an error to happen. Making that simple conversion. It's just a simple trick problem, but it's easy enough under the pressure test to just screw that up and so if you take something that's correct, it has here and move it to here but make a mistake, I can't let that ride, you goofed up. Would that just ignore the simple trick? No. Oh, yeah, I had the velocity in it. Well, no, what you'd end up getting, actually I guess I drew it on the wrong vector, you have some acceleration like that and then that one would break into XY components. Some students are very tied to XY proportions. So that one, I've written down 9.7, I thought you said 9.8, I was hoping for a void argument, but third one, they're actually four because we've covered more material on that one. There was the third one, it's a problem, we've been looking at those on Friday that actually not unlike the kind of thing you do if you ever had to winch a fallen climber out of a crevasse, just the kind of thing they set up. So given that block A is moving to the right, possibly an acceleration of block A. I'm going to look at this actually. For what I said is advice for a coordinate system, I think I gave it two particular pieces of advice for coordinate systems. Keep it fixed, wherever you put it, don't attach it to one of the moving objects. You can, it just makes them more difficult. But the other thing was not between the two objects, now this is where the curve ball is here because we have two directions, I'm going to talk to them, they have been retreating. I'm on I am with my lawyer, you have to pay attention. Remember what it is, the basic thing you need to solve these problems. The premise on this whole thing is what? Yeah, the length of the rope. So however you can find that, I don't know what that means, huh? Yeah, that's a magic pulley. There we go, put the thing on. We're using it for a coordinate system, still kind of thinking. Share it with Alex and he didn't like it. Actually I don't want to write anything this way. Write anything down when it's wrong, you can erase it. I don't want to waste my time here.  And sketch them. That one's in there. That one's full of talent. I'm in a pencil group. I try to use a pencil and it's like a snap when I'm out of there. What'd you do? Here if you do that enough times. These three lines? Yeah. Well, no, they're not even right here. They're not pulling. You're the top pulleys, Well, it doesn't matter because that pulley moves and is as it does, the length of that will change, that will change, that will change. Once you've found the length of the rope, remember what the next step was? Oh, and you didn't watch the video? I didn't. It's not that long. All right, the whole deal is if we can find the length of the rope, then we take the length of the rope will be some function of the position of the two objects plus some other stuff that we call constants. That's things like the amount of cord wrapped around a pulley. That's just never gonna change. No matter where the object is, that doesn't change.  So it all had to do with where A is and where B is and then all the other stuff that never changes. And then we take the time rate of change of the length of the rope. What should that be? The rope doesn't change length. So now we have this as a function of the velocity of A and B because they integrate as well. And then what's the time rate of change of constants? Zero. So all that's left is some functional relationship between the velocity one and the velocity of the other. Which is exactly what I asked for. Gave you the velocity of A, asked for the velocity of B. Then you take the derivative again and you have a function that relates the acceleration, which again was the last part that I asked. So the is really the hardest step because these were very simple derivatives to take, which is all done. What'd you do? Did you even look over her shoulder? I would at least see what do we've got because maybe you should have made a little mistake and it's pretty easy to learn this. Well, where'd you put your origin? Here? Like where B and A, like? Where they intersect, sort of? Yeah. So you did something like that? Yeah. Okay. And then measured from there. That would be the distance down to B. How do you handle A? Does that work? Maybe it would rest more easily with your I if you even wrote that. Would that change anything? Not really, no, not at all. All this motion's in one direction, all that motion's in the other. They're linked, of course. So let's see then how to do the length of the cables in that regard. So we have this piece of cable, which is YB minus whatever that piece is. I call that constant. That's a constant, all right? So we've got YB constant. We'll just dump in there. So that little bit there above that line is a constant. We'll just chop it off, dump it over there. We've got the YB minus whatever that is. We've dumped it over there. What about this one? The second cable, the easiest way to do it, make sure you don't want to skip any parts. What about this cable? It's also YB minus that part, which is a constant, and minus this part, which is a constant. So it's another YB, put a 2 in front of there. I don't know how many we get. Now we've got two things dumped over there in constants. What about this cable? It's YB minus that amount, minus this little amount. But those two are constants, aren't they, right? All right, so that's a third YB plus a third little bit dumped into the constant bucket, where you have trouble. Yeah, I did. All right, so we've taken care of those three areas. They've been comfortable with those three.  Well, that was this one. Now we have that one. We've got this one. OK, so that's xA minus that little bit, just more constant. YB plus 2xA, dj, that makes sense? Do we, that's what you've got up there? Pat, come figure that out? Yeah, you take the time derivative of that, 3y dot b, the velocity of b, well, we're asked to find that, plus 2x dot a, which we're given. Because everything else is a constant. Both the length is a constant, and of course, the constants are constant, so they all have to reverberate to zero. And b, which we are asked to find, is what, minus 2 third, whatever x dot a is. Don't even care. But we are given that, minus 10 thirds. What's that, 3.3? What's the minus mean? Yeah.  Yeah. So this means that y dot b is decreasing with time, which means it's going up. As it would, you'd expect if a was going to the right. So if x dot a is positive, y dot b is negative, advice person. If a is getting bigger, b is getting smaller, advice person. So minus sign in terms of what's happening to the coordinate we set up. We could have done y b down to be negative, I guess. It's just a distance. So that's the best left positive, I guess. We can just take the second grid over the bad equation. Straight off. I'll give you another one of those. We've got that, and try to clean the board. Put a little bit more practical application to it. A winch set up here, for some reason named C. Oh, this is the winch, 4.2 centimeters. Angular velocity of the winch, 47.6 radians per second. Should have given it an r, d, m. Find the velocity of C. After a conference around there, we actually had that in there, pi r, for each of the different polies. Then quickly realized it's a constant. So we don't care about the details of the constants. Yeah, that's right. That's the easy part. Moving and between objects. Drew it there, but that's not having to measure anything. So we drew an origin, then ignored it. We used a y. Doesn't matter. So the length of the rope. In those terms, it might be more cables wrapping around that. It's always the second person to go is the first hit me. Let's say it's winching up. It wouldn't matter. The equation's all going to be the same, whether you have a negative sign on it or not. You do it? No. 3yc, you're getting that a lot of the answer. You know something's wrong. Because if you've got 3yc, and you take the time to rid of that, yeah, so that's not it. That's not going to work. Unless, well, if we turn the system off and go home early, I guess that handles it. Somehow you've got to get this in there, the fact that the cable's moving. No, no, non-stretchable cable. I bought it from Ace, got it from Earl of Ace. He was pretty dumb to buy a stretchy cable, so I imagine in especially large crane design, they have to take that into account. Luckily, we're not there yet. Don't just save this for Friday. We're on negative sign, which should give us a hint. What do you do? It's all up there. Give you that hint. Let's see. Maybe we can. We've got to get the fact this is turning in there somehow. A little mark on there maybe called it A. It's like A. It's the speed with which that rope is moving up that determines the speed of the whole rest of the system. This system, you could take out this winch, run this up to something else, and it wouldn't be any different than any problem we've already done. Because you know the speed A is moving. That point A, it's just the speed of the winch. Minus, well, there's some constants or something up there we're not really concerned with. We want to do that whole length of this cable, I guess. So its length is yc minus, oh, we have to worry about all those things. I'm going to manage this. Not worry about that. That's a constant. That's a constant. So that's not a big deal. That's a constant. What was the other dot there? Where? Here? Length c. This length c? Well, it's a little confusing. Length b. Make this length b, but that's changing. Let's do this. Let's start from the other side.  Because that's a constant. That's a constant. The amount around each pole is a constant. How about this length? Well, y a only if it's perfectly level with that. But as this is going up, that's going to go down. You think, aren't these two lengths, what if we took those together? All we care about is we take track of the entire cable length.  Oh, sorry. You could, I guess, but you'd have to know you just need to locate some other things. You need to locate this. I would guess you'd have to locate that fully. And then, well, that one's a fixed distance away from that one, so that wouldn't be a concern. So it would come out outright to be the same thing, the point where we know it's moving.  It's yc minus ya, which isn't constant, minus that, which is. Length of the cable, these two cables taken together. Total distance is yc, top to bottom, minus this amount, which is constant, so we're not worried about it. Minus this amount here, yc minus that amount, it's as if we now took this off. We just have now yc minus ya, which is the point. This is the length to this point because we know that velocity from the speed of the winch.  We don't care if they're minus, plus or minus.  But we don't care if it's all yc. So we want to pass those specific constants. That doesn't matter. And we're going to go with yc minus the ya. And minus a constant. That's it with you, Pat. Oh, yeah. Did he help, Alex? Is that a good explanation? I'm just too lost. All right, here. Maybe there's just a different way we can draw this. So let me try this. I don't know if this will work. Let's try if this will work. Here's a length of cable that's yc long. If I had a piece of cable like that, it would reach down to C from the top. Now, I'm going to take out of it that amount, which is no trouble because that's a constant. I think I just got it. And then I'll take out this amount, but that's ya. So I have yc minus a constant, minus ya. So yc minus ya plus some stuff in the constant. I realize that we're just the second pulley was also moving upwards. This pulley? Yeah. These two? Isn't that what's causing this? Yeah. Well, if cable A is going up, point A on the cable is going up, then that pulley is going to go up as well. Cable doesn't change to that song 0. Or we just had yc up there, or free yc for L. Why only put the time variable to 0? Well, when you originally had L equals 3yc. Yeah, why did it go to 0? Because the length of the cable is constant, supposedly. And that's what this is supposed to represent. Plus constants. So it can take the time derivative of it. That's 0. But the time rate of change of the length of the cable is also 0. That doesn't mathematically fall from here. It's a restriction we have on the problem that this is a non-stretching cable. The length of the cable itself is a constant. So if you set that to 0, then you don't have anything left. There's no way the velocity of the pulley, the winch, sorry, was in there. I mean, when I first looked at that problem, I automatically just set it up like this. Why is that? Here's what Jake had, and he asked the question, why is this wrong? This is how he set it up originally. He had called that w, called that distance w, and then that distance c. And you said what the length of the cable then is w plus c for this first piece? It did it like a what? Like a track, like starting at the winch and falling down. So you said that this is 1, 2, 3w, right? Plus 1, 2, 3c minus a couple constants with a k for constants, because you have a c in there. And then l dot equals 3w dot plus 3c dot equals 0. It doesn't make sense because the boys aren't doing anything good. Everybody see trouble? It's doable, but there's a big, huge extra layer of complication in here. Just end up having too many variables to build a software, right? I think it's great to just don't know what w dot or c dot is. You don't know what w or c dot is, so you can't, we need c dot. Well, actually what you need is w plus c dot. Plus this point right here to which he's measuring c is moving. This point right here is moving. So he's essentially put his origin on a moving object, this point, and between the two objects doing the moving. So he was able to violate both of my recommendations on where to put the origin. I didn't know I was doing that. Well, you can get there. It's all screwed up by the fact that that point there is moving. Now if you can figure out how fast it's moving, then you can account for that in these different images. But I wouldn't even want to touch that one. The velocity of a, just put that in there. Velocity of a, I think it was two meters per second. Do you want another one? Because you like drawing? You know, if you could bring in colored pencils yourself, I remember when I started doing the first professor I had who used colored pencils. I said, boy, that works great. Took me about half a semester to take into my notes that same way. All right, so here's, I'll leave her being part of a crane or something, maybe an overhead crane here, unfixed pulling below it. And that's where our load hangs. This is the second. This pulley here, so I'll put some little rollers on it because it's attached to a piston that pulls it in and out. All right, you got that? Before I put the cable in, pay attention to what the cable does. Around those two pulleys, I think there's slack in the line. The piston actuator must move to raise the load two feet.  Is that what you meant? Let's label everything here. If you want about any one of the pulleys, make sure you know which ones move and which ones don't. Now there's no slack along, and I just got excited taking the corners as a good call. We could use a chain here. And then some of these pulleys could be like bicycle derailleurs or change gear, change the radius of the pulley. The radius of the pulley isn't a constant as we've been using it. All right, I guess we have to make this a get-up class question. This is going to go up two feet. How far is that one got to go? Gotta make sure the piston's big enough. The actuator. Set up your measurements in terms of what's moving from something that's fixed. For example, we could do and we'd know where F is. Point E isn't moving. Same as the actuator. So the length of the cable. Let's see. XC plus XC plus some constants. Plus this piece here and that piece there. You're okay with these two cables? This cable. Well, that's a constant because this isn't moving, that end isn't moving and this is a constant. So all we're left over with is just the two vertical parts here. Which is two YF. So for F to go up two feet, the end of the actuator arm C has got to go which way? XC increases. Because these two are all together accounts. So if YF is decreasing, XC is increasing. It's got to go that way. Which would certainly make sense because if you take more cable up at the top you're going to have less down here. So that system is really too many things for mechanical advantage? No. Other than whatever was doing in this direction is now doing in this direction. Which itself may be an advantage. Maybe you need to get your mother in law out of a crevax. Sorry, Nana. Just kidding.


For the safety of your smile use pepsidon twice a day see your dentist twice a year Lever Brothers Company presents the pepsidon show my friend Irma created by Cy Howard and starring Marie Wilson as Irma with Joan Banks as Jane Friendship friendship just perfect friendship when other friendships have been forgotten There's will still be hot Being expenses so high a girl has to be mighty careful how she invests her money Me Jane Stacy. I've always taken great pride in having a good sense of values That is until I met my roommate Irma Peterson There I made my first economic blunder. How do I know? Well one day I said Irma a penny for your thoughts You know I got gypped Don't get me wrong. I love her. It's just that Well, for instance the other day I was reading the newspaper and I said Irma. Yes, Jane isn't this terrible? After all the work and expense they find that that 200-inch mirror on Mount Palomar isn't perfect It has a small wave in it. So what all the mirrors at Coney Island have ways in them and they make money You see what I mean. Well, perhaps some other time. I'll try to straighten Irma out But today I'm just too annoyed to even think straight Jane What is it sweetie? What's the matter with you? No, I don't know. I'm just not myself today I'm so nervous. I could jump out of my skin. Well not in this weather Jane You'll catch pneumonia I'm sorry I mentioned it. Oh, no Jane. I'm your friend and I want to help you I wish you'd tell me what's making you so nervous. All right. I'll tell you it's my job my boss, Mr Thompson, but I thought you said he was a nice man Well, he is honey, but he's just too old to be in business. He's so absent-minded. Oh, don't worry about it Jane my boss. Mr. Clyde's always saying my mind is absent, too Yes, I know honey, but you don't understand it's it's well, it's just that the job is so monotonous I'm tired of this eternal struggle to make an honest living. Well, Jane There's only one way out if you don't want to be honest get married Me Jane a girl has only two choices Alex explained it to me either girl works and supports herself or she gets married and supports her husband I Am I'm not thinking along those lines. I was I was just thinking of quitting my job Why don't you it's not that easy Irma? I couldn't afford to give up my job unless I had another one to go to Yeah, I'll bet if you talk to Richard he let you have your old job back Richard.  Oh, yes, it it was. Oh, but I couldn't ask Richard My pride would never allow me to well swallow your pride Jane and then if he turns you down you won't go away with an empty stomach Irma in case you've forgotten Richard already has another secretary. Oh, you mean that Carolyn Benson? Yes, and for the life of me. I don't know what Richard sees in her. Well, she's pretty and she has nice legs She's bow-legged.  I wonder if he was talking about her work or oh, no me professor Hello, Jane, you know my my two little Christmas trees One covered with tinsel the other is professor. I'm not in the mood for any of your jokes today It's all right with me Janie.  What's wrong? She's disgusted with her job wants to quit Listen Janie jobs don't grow on trees unless of course you are in the lumber business. I Know professor not taking me. I'm not happy working in the gypsy tea room, but I have to make a living You know, there's an old saying Everything that goes up must come down. What's that got to do with me? Nothing. This is a saying for elevator operators Oh professor, I was only trying to cheer you up Janie Seriously, if you don't like your job, why don't you talk to Richard? Maybe you can go back to work for him Oh, no, no, I just couldn't maybe it's my foolish pride. I know what you mean Janie Pride can be a very bad thing for a person You know years ago in the old country when I was young I met a girl She was beautiful rich talented and I wanted to marry her but I was poor and my clothes were rugged So I stopped calling on her your pride. No, her she wouldn't be seen going out with me Look Janie Richard has always spoken very highly of you. Why do you think he wouldn't hire you back? Well? Well for one thing he already has a secretary that Carolyn Benson, maybe there's some way we can get rid of her. Oh, I know how to do it. You do sure Jane Call her up and tell her that Richard murdered his last secretary and you wouldn't want her to suffer the way you did Irma Jane I wish I could help you but you still have a job. So take my advice Don't ditch one job until you have another and speaking of ditches. I think I'll go back to the one I live in Yes, sweetie, I know how you feel about your job and if you're afraid you won't get another one Don't worry about it. I'll speak to my boss. Mr. Clyde. You're sweet honey But I thought he had enough help. Well the other day said he expected to have an opening for a new girl most Anytime he did. Yes, it was right after I spilled the ink well on his new suit Come in Hello girls. Oh Mrs. O'Reilly. What's the matter Janie? You look so depressed. Oh, it's nothing I I was just thinking of quitting my present job. It gets me down Oh, I know how you feel honey making a living can be very trying at times You think I like being a landlady and taking the abuse I do from the professor Just listen to this note. He left on me door this morning If I was a knight in shining armor, you would be mine even though it took force.

Okay, good morning, everyone. Welcome to BC 214, our course on developing the human spirit. Thank you for connecting and joining the class this morning. I would request somebody to lead us all in prayer and then we'll get started. If somebody could please unmute your mic and to spray with the class, we will get started. I would like to pray. Okay, I will pray. Go ahead, Maggie. Okay, let's pray. Holy Father, we thank you, Father. Thank you this morning for giving us another opportunity, Lord, to come and learn about how to develop our spirit, Lord. We pray, Father, as our pastor teaches us, empower you, Lord, and also open our heart, open our mind, and open our spirit, Lord, so that we may receive the prayer of this Father in the mighty name of Jesus Christ. Amen. Okay, thank you, Maggie, and good morning, everybody. Once again, thanks for connecting to this class. We are going to continue talking about the human spirit. I will quickly review what we did last week and get into the next chapter, which is chapter three, and then maybe we'll have some time also to start talking a little bit about what we're going to do in the following chapter, or maybe even chapters. So let me just go ahead and quickly share PDF. All right, so we looked at this. We finished, actually, we finished chapter two and this quickly reviewing.  We also said that this hidden person has character traits, as we saw, gentle, being quiet, and that is enduring beauty, and that's very precious. That's what God looks at. We also looked at an example where Jesus is talking about what kind of people you are, what manner of spirit you are, and that's expressed then through the actions and reactions that people have. Matthew 15 brings it out in Matthew 1519. Jesus said, out of the heart proceed these thoughts, these actions, these behavior. So what's in the heart, the inner person, is expressed then through the thoughts and the behavior and the actions that we express. We just outlined very quickly the faculties of the human spirit. What we are saying is there's like a parallel set of faculties in the human spirit, which we can see very clearly in scripture. The human spirit has the ability to see, hear, feel, smell, and taste, and of course, all of these are in the spiritual sense. We will go into the details in a subsequent chapter, not the immediate next, but in a subsequent chapter. Then we also outlined the seven functions of the born again human spirit. That means what does the human spirit primarily do or functions that it serves. So we listed out the seven, we'll look into each of these in detail, talk about the conscience, knowledge, knowing, communion, or fellowship. It's also a container or repository, or it has the already, if you want to use the word DNA, it's the expression of the life nature of God. It also has identity. This is who we are. It also can do things, take action, and it also can keep growing, increasing in strength and maturity. So these are the seven functions of the human spirit, which we want to develop. So what we are really talking about as we progress is that our goal is if we can develop our faculties and the functions of the human spirit, we will be in a good shape, not to serve God, to walk with God, to serve God, and to do the things he wants us to do. And so we're going to learn how to develop the faculties and the functions of the human spirit. And we also, in closing, we said the born-again spirit needs to be nurtured. We need to be strengthened. So we covered till here. I just want to mention this. What we will see in chapter three, we're going to outline seven practices to develop the human spirit. These are things you have already been learning in the Bible College. We did, even in the last semester, when we talked about keys to supernatural ministry, we touched upon these seven practices. And so I'm going to bring them to us again as a way of reminding that this is how you develop your born-again human spirit and just to follow these practices. But here's what I want to say. And we will prove this. We will show this in scripture in the subsequent class that the human spirit has a range or can experience a range of things. I'm using the word things, but it can go through a range of experiences. For example, we will see all of this in scripture. The human spirit can go through pain. It can be broken. It can be contrite. It can go through anguish. It can go through even anger and resentment towards God. Or it can go through some very positive things. We see in the Bible that the human spirit can receive inspiration from God. It can search out things about God, about ourselves. And it can be strengthened in God. It can be filled with the very grace and the character of God. So the human spirit can go through a range of experiences. And what we will see also in scripture is that what the human spirit experiences is then released or portrayed through the soul and the body. So if, for example, if the human spirit is in anguish, it's broken, it's crushed, it's fainting, it's failing, then you know the soul of the person is also pulled down and tends to give up, tends to quit. I can't handle this anymore. And then bodily, physically the person begins to, what we would say, be in a depressive state, meaning they lose all the zest for life, they don't work, they don't do things. But where is it coming from? You see, we will see in scripture that when the spirit is crushed or it's failing or it's overwhelmed, it's in anguish, then the soul gets affected and then thereafter the behavior gets affected. So the premise or the principle we're going to put forward as we develop this is if we can keep the human spirit strong and healthy, then you're going to have a healthy person. No matter what the situations and circumstances bring, because of course in this world we are going to go through, you know, all kinds of things, they're going to be challenges, they're going to be difficulties, they're going to be obstacles, they're going to be hurdles, all kinds of things, right? If we can't prevent in the sense, you know, those things are what happen in the world. But if the human spirit, if we keep our spirits strong, healthy, then what's going to happen? The soul and the body are going to be also strengthened and we are in a very strong position to live it toruously in the middle of all the conflict that we face. So these seven practices that we are going to outline here in chapter three, which all of us are aware of, you know, it's not new, we've talked about it before and we are all aware of these, but if we consistently keep in these seven practices, we will develop our human spirit, we'll strengthen our human spirit, keep it in good shape, you know, if you want to just put it in simple terms, keep the human spirit in good shape, so that when there are things from outside trying to crush, you know, trying to break our spirit, trying to hurt our spirit, trying to hurt the very person, then because we are strong in the spirit, we can be strong in our mindful and emotions that is emotionally be strong and also physically our body is also energized.  So these seven practices, I know, we'll just talk about it, the scriptures are there, I've mentioned them, these are things that are familiar with all of us but the key is to consistently practice these things. So how do we develop our born against spirit? That means how do we strengthen the inner man? Through what God has made available to us, we're not talking about other extraneous methods and means, we're saying, okay, this is for the believer, right, for the believer. How does the believer train his spirit so that the spirit faculties are strengthened, sensitized to God and to his work and the spirit functions are strengthened in the believer. How do we do it? First, it comes through fellowship with God and at the very beginning of this course we mentioned here, right, God is spirit and he's made us spirit beings and that's why we are in that position even though we are living in a natural world because we are spirit beings, we are positioned to commune with God, the fellowship with God, spirit to spirit. So that fellowship, that word fellowship simply means to share everything, in one sense, it means to partner, to share everything, to have everything in common, that means we share our heart with God and he shares his heart with us. So this fellowship with God, and you find here in these scriptures, in 1 John 1, John the below what he says, in our fellowship is with the Father and with his son. 1 Corinthians 1-9, it says, we're being called into fellowship with the Lord Jesus Christ. 2 Corinthians 13-14, he talks about the fellowship of the Holy Spirit, the communion of the Holy Spirit. So really, the believer, if you look at these three references, the believer is fellowshiping with God the Father, God the Son, God the Holy Spirit. There is, we are fellowshiping with God, the Godhead, we are in communion, we talk, we worship, we pray, we listen, so we share in our heart, he shares our heart. So it's a place of friendship and that friendship can become stronger and stronger through worship, prayer, and the word of God and obedience to God. So the first key or the first practice for all of us to make sure that our human spirit, the spirit of within us is in good shape or keeps itself in good shape and keeps growing, keeps developing. The faculties are being strengthened, becoming sharper, the functions are becoming stronger within us. It comes through communion, fellowship with God, friendship with God. Now, we understand that in order to fellowship with God, we have to walk in the light as he is in the light. You know, therefore, we keep sin away, we keep wrong things away, we guard the other place of friendship with God. We guard our place of fellowship with God because it's important to us. We have to walk in the light as he is in the light, then we are fellowship one with another. So fellowship with God is important. Secondly, learning the importance of quietness and communion. Now, Isaiah 30 and verse 15, could somebody read that for us? I mean, I know some of us can quote all of these verses but it will be good to turn and read it. Somebody could read that for us. Isaiah 30 and verse 15, please. Isaiah chapter 30 verse 15, this is what the sovereign Lord, the Holy One of Israel says, in repentance and rest is your salvation, in quietness and trust is your strength, but you would have none of it. So I'm just looking at the second part of that verse, second half of that verse. He's saying, of course, he's calling his people back to himself, right?  And then he continues, in quietness and confidence will be your strength. But you didn't want to have that. You didn't want to listen to me. But God, so God is telling his people, you know, you get back to me and just get into a place of rest, quietness and confidence. And then you will be strengthened. You will have strength. God is actually telling us, you know, is giving us the secret of being strengthened. You come to this place of rest and quietness and confidence in God and you will be strengthened. So we must learn to do that. That means that's why we have this phrase quiet time and we, you know, we didn't say have your quiet time every day, things like that, which, you know, it may sound very, you know, something that's very trite or cliche type of things, but it was actually very true. It was actually very true that on a daily basis or at least let's say regularly, frequently, we need to come return to the Lord, meaning just turn our attention completely on him, come into this place of rest and quietness and confidence before him. And that's where we will find our strength. The strength, of course, is not talking about physical muscular strength. He's talking about that inner strength of the inner person.  I mean, okay, that's a choice they make, but I'm not saying we have to go to that, but what I'm saying is on a daily basis, we recognize that in quietness and communion, this place of quietness and rest, we are going to be spiritually strengthened, strengthened in our inner person. So you make time for yourself to be in quietness. Just, you know, leave a bit, just pause everything else for some time, half an hour, one hour, two hours, whatever time you can make and be in quietness before God. And it is in those quiet moments that God can give us revelation. It is in those quiet moments, a lot of things happen and we will see. Now basically, these five faculties of your spirit are touched by the very presence of God by God himself. So your faculties are given, I'm talking about your spirit faculties, your spirit faculties are given an opportunity to encounter God in these moments of quietness.  But in these times of quietness, the spirit faculties are given stimuli. Your spirit faculties are sensitized to God. So the more we spend time in quietness before God, the more sensitive we can become to God, spiritually, spiritually, I'm speaking, right? Spiritually, become more sensitive to God. Your spirit faculties are able to recognize His presence. You can recognize His presence anywhere. Now, generally, you know, when we have great times of worship, we are able to recognize His presence. You know, for instance, yesterday, in our East Church, that's our eight o'clock service, the eight o'clock service, you know, Pastor Roshan was leading worship. It was just him alone on the guitar. It was such a wonderful time. And by the time that we finished, you know, that, I don't know, maybe 30, 40 minutes of worship, the hall, the auditorium, and we didn't have many people, we just had 50 or, sorry, almost 60 people in person, present. But we could feel the presence of God. It was just wonderful. Now, of course, we went through a time of worship. So there's that time of just fellowship with God.  Wonderful. Well, if our spirit faculties are sensitized to His presence, you could be walking down the road somewhere. You could be in a shopping, you know, mall. You could be in a very crowded place. But because your spirit has been sensitized through times of quietness to the presence of God, to God Himself, you could encounter the presence of God anywhere, even when there's, you know, disturbance physically outside of God. I know you're present here. So that's the importance of quietness. It's a place of strength, strengthening. As we've seen, Isaiah 30, 15, it's also a place of sensitizing or becoming more sensitive to God Himself because in that place of quietness, your spirit faculties are receiving stimuli or being stimulated by God's presence Himself. Right. And we know the scriptures.  It kind of goes with what He said here in Isaiah 30 and verse 15. So let me just try to go fast. I won't finish this today. It's number point number three about strengthening or developing our human spirit is, of course, to feed on the Word of God through meditation. Matthew and we know again these scriptures. Matthew 4, 4, man will not live by bread alone. That is the natural food. But by every word that proceeds from the mouth of God. So Jesus is drawing, of course, this is from the Old Testament, you turn me. God is telling us, look, just as natural food provides sustenance in life to the physical, His Word is that to our inner person. So the Word of God is food to our inner person. It's food. So you obviously, if you want to strengthen the inner spirit man, the spirit man needs food, needs to be nourished. And the Word of God, God is saying, my word is that nourishment. So if you want to strengthen our inner man, feed it with the Word of God, feed it with the Word of God. Now, of course, when we talk about feeding the Word of God, we have to understand. We are talking about a mental assimilation of information concerning the scriptures. So we're not talking about, you know, just mentally, okay, I, you know, I study the Hebrew, the Greek, or I study the, I do the survey of the book, I understand the background and culture and the literary context and meaning and all of that. You know, that's a lot of intellectual assimilation of information, which doesn't necessarily nurture the spirit. So what are we talking about? We're talking about discovering truth. It's the truth that we discover through the written text that nurtures our spirit.  So he's telling them, look, you search the scriptures, but those scriptures are, they contain revelation, they contain hidden truth and they're pointing to Jesus Christ. So it's not about just looking at the text, but looking at the revelation, the text is bringing to us. And that's where even these Pharisees who studied the scriptures, you know, they, they missed it because they were just looking at the text. They couldn't see that the text was pointing to Jesus, right. So as we feed on the word, our desires, God, open my eyes that I may behold wonderful things in your word. And as we train ourselves in the word, the, the word of God, maybe I made a mistake, I think it's Hebrews 5, not Hebrews 4, must be a typo here. Yeah, amen. Let me just look at this, Hebrews 412, but also, yeah. Okay, so here I just meant, you know, both Hebrews 412 to 14 is good, but what I actually meant was Hebrews 5, okay. Hebrews 5, it's talking about how, through the word, as we feed ourselves with solid food, and we saw this last week, the spirit man is nurtured and we become mature into being babies as we feed ourselves with solid food. So there's this development of the inner person.  I want to know the truth that's in the word. I want the truth in the word to build up my spirit, not just an intellectual assimilation of information in my mind about the Bible, but I want the truth that's in the Bible. All right, so that's feeding on the word of God, and it comes through meditation, and it's tied into this quietness and, you know, as you're quietly in the presence of God, and you're meditating on his word, you begin to see truth, you begin to receive revelation, and that develops the spirit man. And before the way we develop our spirit man is by confession of the word, that means we need to speak the word with our mouth.   I want you to say my word. And the confession of the word of God is going to build faith because faith comes by hearing the word of God, and you be your own faith builder in the sense that you speak the word of God to yourself.   It's going to strengthen your inner man. So this practice of confession of the word again is a very important practice for us to keep speaking the word, say what the word says, let your spirit man hear the word of God. Number five is praying in tongues. This is again something God has given to us to edify ourselves. You know, if God felt that something was important and that he should give it to us, then we should just accept that well, God knows best.  Okay, so God knows best.  And in verse 21, he says, keep yourselves in the love of God. And it's very interesting, both in verse 20 and 21, it's like do it yourself kind of instruction. You know, do it yourself.  You do it for yourself. What?  That's verse 20. You do it yourself.  So it's entirely up to you and me. We can build ourselves up, how praying in the Holy Spirit. And then verse 21, keep yourself in the love of God. Again, so this is a do it yourself thing, right? There may be many reasons why you and I would feel tempted not to walk in the love of God. You know, people may do all kinds of things to us, but we make a choice. I'm going to keep myself in the love of God. And how do I do it? By praying in the Holy Ghost. So God has given this to us and he has explicitly stated that praying in tongues is a way for us to edify ourselves, which is build ourselves up or strengthen ourselves. It's a way for us to build ourselves on our faith and to keep ourselves in the love of God. So this is so important, praying in tongues. So you spend time praying in tongues. You're just using something God has given to every believer, right? And again, you know, God is not partial.  And the others, you say, sorry, this is not for you. No. If this is a mechanism or this is a means to build ourselves up spiritually, then God is a fair God, a just God. He's going to make it available for every believer. You know, that's why we say every believer can pray in tongues. It's up to you. Of course, God is not going to force you, but that's available to all of us and we encourage everybody to spend time praying in tongues.   Suppose you're to drive somewhere, you know, praying tongues and drive, if you're by yourself, of course. So at every opportunity where you're by yourself and, you know, you are not doing something that's, that's, you know, requires your full attention, then just pray in tongues and do that. You know, you can pray in tongues and drive, you can pray in tongues and walk. So make use of every opportunity to pray in tongues. And it's just a wonderful way to strengthen your inner pursuit. You know, man. And very often when I'm praying in tongues, I'm also listening to the word of God. So, you know, thank God we have these audio, audio things on the phone and we can put headphones and you can pray in tongues, you can be listening to the word, you can be doing, you know, you achieve both around the same time as last two things and I just started to finish this. So number six is we need to exercise our spiritual faculties and functions of which walking in love is the highest. So a very important part of developing our spirit man here is to exercise our faculties and functions, what we have listed before. So the five faculties, what you see, what you hear, what you feel, what you can sense, what you can taste and don't worry too much about taste, but if that is stimulated, that's fine. But at least what you see here and feel in your spirit, you exercise those, keep using them on a daily basis and functions, the seven functions of the human spirit, keep exercising them. Right?  If you have to, you know, work on a proposal or work on a sermon or if you have to provide counsel to somebody, you know, all of these things, the day-to-day things we're doing, you tune into your spirit faculties to see if God is saying something there and try to draw out of that. We will see in our next class, you know, as we come up, how God inspires, you know, through our spirit faculties. Right? Just as a, you know, way of introduction, let's go to Job 32 verse 8. Now, we will get into this a little in-depth in the coming weeks, but just to show you what I'm saying, Job 32 verse 8, somebody could read it, please. Job 32 verse 8. Job 32 verse 8, shall I read first? Go ahead, please. But there is a spirit in man and the breath of the Almighty gives him understanding. So, there is a spirit in man, so it's a human spirit. The breath of the Almighty, the inspiration of the Almighty. Where is it coming? It's coming in your spirit.  So, we have to exercise this. Right? So, when you need whatever, you may have to make so many decisions, what do you do?  It could be a business decision, it could be a family decision, it could be, you know, whatever, you know, it could be a ministry related decision, whatever, there's so many things we all have to do. But what I'm saying is we have to exercise our spirit faculties and functions. And in that place, in that place, in your spirit, God is giving you inspiration when you need understanding. The breath of the Almighty, the inspiration of the Almighty gives you understanding. But where does it come from in your spirit? How will you pick it up with your spirit faculties? Sometimes God shows you, you see, sometimes the words and information coming show you here and now. Sometimes it comes as impressions, as feelings, and so you feel, right?  But this is something we have to exercise. If we don't exercise, we won't develop those faculties and functions. And as what's going on in this 13 tells us, the highest is love, that means everything has to be kept under that motivation, right? So the expressions of the things that God inspires us to do, just guard it and keep it in love, right? So don't be motivated by other things with jealousy or pride or competition with people. No, no, no. Keep all those things out. Be motivated by love. So example, suppose you're praying and saying, God, what do I need? I'm just saying, you know, practically, you say, God, what do I need to grow something?  If you're in business to grow the business to, you know, so you're praying about increase, you're praying about growth. Wonderful. And you're possessing yourself to hear from God. Wonderful. You're looking for the inspiration almighty to give you understanding. Wonderful. But make sure you're motivated by love. Don't desire growth to compete with somebody else or outperform somebody else or out of jealousy towards somebody else. No, no, no. You're exercising your finest faculties and functions to do the things God has called you to but always keep everything motivated by love. And that's the highest because if we step out of love, then those things don't matter. 1 Corinthians 13 says, if I have faith to move mountains, but I don't have love, that doesn't matter anymore.  But if I'm not motivated by love, it doesn't matter. So the emphasis here is exercise of faculties. And we're going to learn more and more how to do it, growing the functions of your human spirit, but keep everything motivated by love. And the last way we develop spiritually, develop in a person is this, by receiving spiritually through other people. And God has put us in a body and his place, you know, people around us so that we can receive spiritually through one another, that we can refresh each other, we can encourage each other, we can learn from each other. There are people who are more experienced than us.  And so what must we do? We must learn to receive spiritually through other people. Okay. So as you let, of course, be careful, don't take anything and everything, but, you know, the right things, as you receive the right things through people, it will nurture us spiritually. We will be strengthened spiritually. Okay. So let me pause, quickly review these seven, then just take questions. So how to develop one against spirit, fellowship with God, keep that fellowship with God, take time to be quiet, to rest, to be in that place of rest, quietness and confidence, because that strengthens and also sensitizes you to God. Number three, the word of God, that's spiritual nourishment.  God gave us this method or mechanism to develop us. Number six, exercise your faculties and functions. Develop that. We will get into the details of the faculties and functions, but stay in love. Right. Don't do it out of any other motivation. Lastly, keep learning through other people because God has given them to strengthen us. So let me repeat one point that I said in the beginning and then we'll take questions. If we do a good job in developing our human spirit, a born-again human spirit, keep it in good shape, then our soul and our body will also be blessed.  It's blessed, but if you allow our spirit, human spirit, we will see this next week. If you allow our human spirit to be wrongly affected, you know, then it's going to pull down our spirit and can also impair or affect our body. I'm going to stop here, just pick up some questions and then let's, let's see what we have. I'm just looking into the chat. Okay, Prabhakar, is it we go before God and wait to hear from him? Prabhakar, I didn't quite understand the question. So this is regarding our quietness and communion. So when I want to ask this, like I heard from Pastor Benny, like he said, he goes to a closet and waits without speaking anything, being just quiet to hear the word of God. So I wanted to ask, is it that you meant to say fast or like, I'll read the word and wait for God. Alright, so okay, I understand the question. Now, so how do we practice quietness? So it's not that we don't engage with God, right? So in quietness, you may, you are first of all, your mind is focused on God, right? You're, you're in communion with God. You are, maybe you could be praying quietly, you could be praying in tongues, or you could be worshiping, or you could also be meditating, reading the word of God, or meditating the word of God. So that is your quietness before God. A quietness does not mean that we should sit or we should be in a place where we blank out our mind, right?  No. Actually, that's a very dangerous thing to do.  Because then that's where, you know, the wrong kind of spirits begin to affect us. So don't do that. Your mind is to be focused on God. You engage with God, either through worship, prayer, or through the word of God. Okay. So in that place, you're also in stillness, meaning you're listening to God, your senses, like we're saying, your faculties are alert to God, right? And, and then we are able to receive from God. Is that okay? Yes, Mr. Thank you. Thank you. All right, let's take up the other questions. I think they're maybe they're all related. What is the main effect of not developing the born-again spirit? Is it depression? Moving away from God, I just not functioning to a full spiritual potential. Can you speak a bit about depression, the spirit? How much is it to do with physical elements and spiritual elements? Okay, so we will, you know, we will get into this in-depth in the next class. And I've actually listed out the scriptures that that show us the different experiences of the spirit, right? So what is spirit experience? And I'll just quickly give a gist of that.  There are the positive expressions also in the spirit. But when we feel these things, what happens? It affects the soul. And you will see it's stated in scripture, I'm feeling in my heart my soul is sort of full, my soul is overwhelmed, but it's starting in the spirit. So there's a close connect, right? We said earlier, between the spirit and soul. Now, in the case, so to very quickly answer, if we don't develop the human spirit, the born again, the spirit of a believer doesn't strengthen himself, there are a lot of repercussions. You know, spiritually, they are weak, they're not able to, the functions of the human spirit will not be there. That means, you know, like, out of the seven functions, seven functions will be weak. The seven, the five spirit faculties will also be weak. They won't be able to hear from God very clearly. Or even if God is speaking, they're not able to pick it up. Why? Because we're not developing the human spirit. So the faculties and the functions are at a weaker level. And therefore, how much they can do spiritually is also therefore at a weaker level. So, you know, these, these basically, the, the spirit man is weak. And so what they will be able to do is not very much. But if the spirit is developed, of course, the spirit faculties and functions are stronger, stronger, they can, spiritually, they can express themselves. So God can work through them well to do what God has called them to do. Now, in terms, when you talk about depression, it's a combination of things. So for example, you know, most often, it starts off with an external factor, right?  I'm not saying always, but most often happens like this. But the spirit is not strong enough to sustain a man, you know, so Proverbs tells us about this, we will see it next class. If the spirit of man, a spirit of man is able to sustain him through his infirmity. But if it is weak and has broken, then how will sustain him? Meaning, the very thing that gets sustained him is now falling apart. So that's why the strength of the human spirit is important. So there's an external thing happening. But the spirit has has not been strengthened to sustain him through that challenge. Then what happens? He falls. When he comes down, the soul also is drawn down.  So most often, that's how it works, right? There's an external situation. The spirit is not strong enough to carry this person through. And then the soul also is pulled down. Now, sometimes the external can impact the spirit hard, like causing hurt, causing, you know, being just pulling, draining every strength in the spirit, whatever that is there. So that adds to the whole cause of or depression. Okay. So it's kind of in a nutshell, we try to look at it. We will go through the scriptures next Monday. And then we can maybe talk about it a little bit more. Okay. Right. So let's pause. So the main thing I want you to take away today's classes, look, these seven practices that we know, let's do them consistently to keep strengthening in a man because that affects a lot of things. And we will look at it in the next class. Okay. Could somebody please close in prayer so that we can then get ready for our, go for a break and then the next class. Anyone, please? Well, Father, we thank you a lot for teaching us on developing our spirits. Lord, through the learning of this Father, Lord, we may fellowship with you and we will come in with you.
