If the only thing preventing someone from killing people is the threat of eternal damnation, frankly they are dangerous and insane. I never think about hell. Literally, never. I'm not concerned about it and I never will be, it is a man-made place meant to scare impressionable, unintelligent men women and children. Still, I don't kill people and I'm a pretty good dude. The necessity of religion, outside of fellowship and organized congregation is limited in my opinion. Human beings crave a sense of belonging. We need to be able to say I am a… "Blank." That's why people are avid fans of sports teams, political parties etc. I often quote the John Lennon lyric, "I don't believe in Beatles, I just believe in me…" -it's a good approach in my opinion.
