Here's an excerpt:
HABERMAS: ... Given your great respect for Christianity, do you think that there is any chance that you might in the end move from theism to Christianity?
FLEW: I think it's very unlikely, due to the problem of evil. But, if it did happen, I think it would be in some eccentric fit and doubtfully orthodox form: regular religious practice perhaps but without belief. If I wanted any sort of future life I should become a Jehovah's Witness.
