I've hit rock bottom a few times in my life and managed to pull myself out from it without religion. Many people have tried to push it down my face and said I needed to get right with god and I told them that wasn't my problem. After many years of struggling I am better than ever, all without 'giving myself to god.' My point is that the fact that so many people need to hit rock bottom to find religon does not really say anything about religion itself but about the people who needed it to get better. I'm not saying it's a bad thing people use religion to stabilize their lives, it's just that if god really wanted people to turn themselves over to him, why would he allow someone who clearly denies his existence to crawl out from the depths of despair to a good life? Isn't that just reinforcing my notion that god is not neccessary?
Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
