Here is one of my favourite philosophers Peter Rollins telling one of his parables called The Singular Answer. He is a rare breed of philosopher and his parables have this way of working on your mind. Check out his great blog over @ www.peterrollins.net and if you want a great book check out his How (not) to speak of God. It was a book that revolutionised the way I think and speak (or don't speak) about God.
