Ever thought about how the world presents itself to you? How do you know things are the way they are? Who taught you to label?
When I was a teenager I converted to Christianity. I was so convinced that there was a God and Jesus was His son, I went around trying to convert others as well - to "save" them. If someone were to ask me: "save us from what?" I would immediately answer "why, the Devil of course!". So why do we believe? The answer is simple: fear of death.
