In the Bible it says that the blind shouldn't lead the blind. Well I am 18 and have recently lost my mom, trying to raise a 2 year old alone, work, and go to college. And I know that I am not perfect, so should I not try to get people that I work with to go to church if I commit sins myself?
Jesus did not say the blind shouldn't lead the blind. He said that if they do, both will fall into the ditch. (So in a sense he is saying don't do it.) What he was talking about, though, was people who judge others without looking at their own sin (Luke 6:37-40), and those who bind their own opinions on others while claiming to speak for God (Matthew 15:9-14). One who knows they have been a sinner and have been saved is not a blind person, but one whose eyes have been opened. None of us is perfect. A Christian is not one who doesn't sin, but one whose sins are forgiven. In 1 Corinthians 6:9-10 Paul lists a number of sins such as adultery, theft, drunkenness, and homosexual acts. Then in verse 11 he says, "And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God." Paul even called himself the "main sinner" (1 Timothy 1:15). Even though he sinned, he could say that his experience with sin helped him to teach those who were still lost in sin. I knew a preacher who gladly told others that he had been an adulterer and drug user. The thing was, though, that he had left that kind of life to follow Christ, and if he could do it so could others. He still sinned, though not the same sins, but God would forgive even them. Knowing that we are forgiven sinners may help us to be more willing to teach others, so they can also be saved from their sins. You are especially to be admired for going through what you have and still wanting to teach others about Christ.
In 2010, seven years after I posted this answer, a person who gave me an invalid e-mail address so I could not respond to him, asked me to take out the reference to homosexuality in this answer. He pointed out that Matthew 15:19 does not mention homosexuality. I agree. But I did not quote that verse. Instead I referred to 1 Corinthians 6:9-10, which very specifically does mention those who commit homosexual acts. Therefore, in response to his cowardly actions by not giving me a way to respond, I will post this on this question in the hope that he will read it. So to the person who calls himself a "straight guy morally opposed to slanderers," be aware that any slander would have been by the person who accused me of saying something I clearly did not say. If you read the passage I did mention, in the Greek, you will find it very clearly says some of those who were forgiven had been "men who had sexual intercourse with other men."
