Funnily enough I can remember the exact moment when I stopped believing in God.
It happened about 15 years ago. I was reading a newspaper about a baby that starved to death because his mother was too ill herself to care for him. The police conducted an autopsy and the only thing in the child's stomach was bits of its own nappy (diaper). I closed the paper then and knew that there was no God of love. It was, as they say, the straw that broke the camel's back.
What followed was several months of depression as I tried to come to terms with reality. It was a big shock to realise that I wasn't going to live forever and there was no magic answer to the world's problems.
I wish I could go back to that state of blissful ignorance of being a JW but I can't, unless I develop amnesia...
