This pretty sums up what I believe.
At first I was Protestant, a horribly lazy Protestant, that believed in God but didn't feel comfortable adhering to all of his supposed rules. Then I asked myself, "Why do I believe in God?" The answer was simple, "Because my parents told me to." "Who told them God was real?" "Their parents." "Well, who told our grandparents he was real?" "Their parents."
This sort of regression made me realize that everyone in my family blindly believes in God because their parents told them he was real as children. Sure, they would claim to have out of body experiences with God and angels and whatnot, miracles and such, but I had never experienced them. I've been open to him (God) in the past, but no matter how much I tried (and no matter how hard my preachers prayed), God never spoke to me or did anything amazing for me. So, I just stopped caring. I guess it's what the Catholics call "acedia" in that I became unconcerned about where I was and what would happen if I died. I mean, if you've been praying to a deity for years and not once has He spoken to you or helped you in some way, wouldn't you get bored? Would you continue to pray to no avail? I saw no need for it.
Shortly after that I began to notice how some Christians liked to use the excuse that "God works in mysterious ways" whenever something (seemingly) inexplicable happened. "Hurricane Katrina hit New Orleans because of their sodomizing and worldliness" or "Haiti was devastated by God for their belief in witchcraft" or some shit. Such attitude towards humanity is disgusting no matter how vile the act may be. I began to question whether God even existed, because if I were him I would have killed some people for screwing up my name.
Thus, I am an atheist, though if a higher power does in fact present itself, I do not believe people are capable of understanding it.
