One of the top atheism bloggers today, Luke Muehlhauser, posted a gorgeous snippet by a Christian who happens to be unhappy with the contents of the Bible, a story which is scarily similar to mine.
Often people ask me when I became atheist, and I can't answer them with a date since it was more of a process, and reading the Bible (the entire thing) was among the earliest steps towards that end... the God I imagined couldn't have allowed things as horrendous as portrayed in the Old Testament. I kept praying, asking God to help me keep my faith, but no one answered :(
