Also, I think that some people in churches are depressed without even realizing it. They are trying to conform their minds to a belief system that they might have issues with internally (such as eternal judgement). They don't realize that some people can more easily believe in certain things due to their personality type. Your personality type affects the way your brain perceives things.
I think the Bible was written with very symbolic stories. But over time those stories have been reinterpreted literally, because most people in general don't have the ability to rationally see such a story the way the original author intended. The stories in the Bible are parables, as Jesus himself said. Or at least was said by the character using his name in that particular story.
