One thing that I struggle with that alot of Christians say is that there is no such thing as an atheist. I think there is, but where atheists have it wrong is that they generally denounce the idea of faith as being flawed. What they fail to see is that they live by as much faith as believers. The believer has faith that there is a God who made the universe and everything in it, while the atheist has faith in the idea that there is a purely naturalistic explanation for everything that exists. As far as rational logic goes, agnosticism is a truer position. However agnosticism is also a position. It is not sitting on the fence.
A good book I have read about this is ‘Finding Faith’ by Brian McLaren. McLaren is a Christian, however he consulted with many of his atheist and agnostic friends before writing the book, and ran transcripts by them as he was writing. The result is a very balanced book, as shown by the reviews it gets on Amazon.
