A question for believers.

For those who believe in the supernatural, an afterlife, etc, etc - what was the single moment you went from a skeptic, or on the fence to a full fledged believer? Or was there one single moment?

I know, I know, there are a lot of non believers out there - hell, I'm probably one of them most of the time. But this question is for believers only - which makes sense because if you don't believe you couldn't answer this question anyway.
