Discuss how Christians should approach evangelism and reaching out to those who are struggling with sin.
Agreed. You can't reach the lost by being a judgmental jerk who makes kids cry. Christ calls real Christians to be compassionate and come along side people in there darkest days, not yell at them to repent as they come out of the bar. There's a time to talk about the consequences of sin but if you don't be compassionate first, nobody will care about what you have to say. Plus, a position of judgment is the worst place to preach from about sin. Paul constantly used his past to lovingly show that he understood where they were right then and he accepted them. When you can say "look, I've been where you are and have felt what you feel", you will have much more of an impact. When people act like this, it makes the world think this is Christianity. Just my 2 cents.
