Occasionally Christian friends ask would I still disbelieve, if I met Jesus in the street. Firstly, I clarify the image. It's usually a young, good-looking white Anglo-saxon male (pre-crucifixion, hopefully - that gets me into trouble!), who performs magic tricks. Secondly, I gently suggest a better image may be an itinerant, devout Jew who advocates circumcision, strict food laws, and sabbath keeping and who sprukes the imminent kingdom of God. And, that he'll either be ignored by everyone or locked up by the authorities. The conversation usually deteriorates from there.
So, what would it take for you to become a true religious believer? Or, is Pascal's wager good enough?
