Poor old fool. (From Psalms 14:1: The fool has said in his heart, There is no God.) Better he wised up late than never, but so what? He's a dime a dozen as an atheist: a little more valuable as a believer.
Actually, Flew is one of the most influential philosophers in the world.
This is really HUGE (no, I don't mean "hugh") news. He is part of the bedrock intellectual base for atheism. I think an earthquake just occurred. Many folks here just don't realize the immensity of this news. I'm not speaking of Flew's salvation, I'm talking about the whole world of ideas.
His comments about Intelligent Design will Phillip Johnson and company a tremendous boost. Morris and Ham may have lost a few points.
I love the line about "I don't thnk its a big deal". That's just a way of saying, "Move along, fellow atheists. Nothing to see here."
As to his not being a Christian, CS Lewis took years to go from atheist to idealist, idealist to theist, and lastly theist to Christian.
This is just a small, first step. He now needs to read The New Testament and accept God's grace and Jesus as his Lord and Saviour before he could be considered a 'believer'.
