Hi Perry,
"Perhaps her [Democratic Fox News Commentator, Kirsten Powers] testimony will shed some light on the kind of dynamic, interactive faith that Christians have . It is sometimes hard to explain except to describe the kinds of things that God does with it . Kirsten's story is pretty typical when God happens."
Despite being an athiest myself, I believe God does exist, but only as a concept within the mind of believers. This makes God very personal and immediate and powerful as the individual. As believers group together in like-minded thought exchange God can become a shared concept and then as powerful and as enduring as the group itself.
Notice how Kirsten describes her conversion in 2006: I woke up in what felt like a strange cross between a dream and reality. Jesus came to me and said 'Here I am.'
The account goes on about her boyfriend praying for her, thinking they needed to break up, her inability to shake off the experience, etc. But... in the end, it is an internal experience, that cannot and should not be confused for objective truth about existence of God apart of what is going on in her mind. Atheist's too of course experience their non-belief, but more often than not you'll hear them explain it in terms of conclusions (even reluctantly so) they've reached after looking at available evidence.
Cheers,
-Randy
