Talking with a youth pastor. And I need some pointers.

I was just wondering what r/atheism's finest minds had to throw at him. He's quite young, and is probably still open to convincing. He studied at NCU. I will be talking via facebook so if you have any tips in general or anything I should say to get the conversation going would be great. Also, any irrefutable facts, good verses, etc are good. He most likely does not believe evolution. And he is a youth pastor at a "assemblies of god" church http://ag.org/
