Quit pitching friends and neighbors your church! Stop treating them like brain dead, late night infomercial addicts and talk to them like humans! If your God is so awesome, prove it! If God makes your life so magical, show your friends. People are tired of being pitched and sold to, give em the real deal.
Finally, a Christian who understands! Most unchurched are not interested in being repeatedly pressured to attend this church or that parish. We don't enjoy being informed we're going to hell, or that Jesus died for our sins - trust me, we've heard it all before. Between the Baptists, Evangelicals, Mormons, Jehovah's Witnesses, and Catholics, it can sometimes feel like you're under siege if you don't attend church. On top of that, the message is ridiculous to us. You might as well be telling us that Spider-Man loves us, or that Superman died for our sins.
That said, please feel perfectly free to be the hand of your God in society. Since he can never seem to find the time or inclination to come down off his heavenly throne to offer any assistance or help, it's up to the rest of us (including you Christians) to help feed the poor, clothe the sick, volunteer to help clean up the BP oil spill, etc. One important thing to remember, though: keep your preaching to yourself, unless one of the people you're assisting makes an inquiry about why you're doing these things. Feel free to take advantage of peoples' curiosity, but don't expect nonbelievers to sit through a sermon because you washed their car or gave them a sandwich.
