Actually, every Christian is meant to be evangelical with the gifts and talents God has given. I don't think you have to explicitly say, "Hey you believe in God, or burn in Hell," actually I think thats half wrong, It's a way of life, and I think that if you proclaim to be something you better back it up. If I told everyone here that I was a better guitar player than Mark, I should find a way to back that up, like record an album, or post a mp3 of my work, so I could back up that claim. But if I said that, but did nothing about it, you all would presume I am a liar, yay?
