Hello and welcome to Unbelievable for another classic replay from the archives. I'm

Ruth Jackson and this week we're going back to William Lane Craig's Reasonable Faith

UK tour of October 2011. For the debate that Dr Craig himself has called one of his all-time

big busy house tonight and there's quite a few people in overflow rooms so when we do break

to questions on the floor, we're going to ask if you can use a microphone and hand it to you

by the stewards so people in all the other rooms can hear. Now to open the case for the proposition

that this house believes God is not a delusion. We're delighted. I'm delighted to introduce

Peter Williams who is a philosopher who works for the Christian charity The Demaris Trust,
