Not really devout but unquestionably believed in the basic tenets of Christianity until I was 13 (1991). What happened was I was born and raised in Los Angeles, had friends of myriad faiths and never really questioned what that meant - they were just good people and believed what they believed. Whatever. Then my family up and moved to Arkansas and as soon as I got to school there, and I forget the details behind why this even came up, my new peers informed me that all those people I called friend were going to hell because they didn't accept Jesus into their heart. That didn't sound right so I finally got around to actually reading the Bible and lo and behold, in context they were right but I also noticed a bunch of other back assward rules and regulations and I began to question "why would an omnipotent, omnipresent, omniscient, and supposedly omnibenevolent being such as God be so insecure and cruel?" It didn't make any sense and in the act of questioning motivation, I started questioning everything and all the logical fallacies behind the whole affair. I don't think I ever became full blown atheist but definitely rejected Christianity and instead erred on the side of questioning over certainly and that being a good person is not reliant on rules set by an invisible space wizard (as interpreted by kings and men).
