Me: There are two monks guarding two doors. One monk speaks only the truth, and one monk speaks only lies. You do not know which one is which. Behind one of the doors is heaven, behind the other is hell. You do not know which one is which. You may only ask one question to either of the monks to find out which door leads to heaven and which door leads to hell. Which question is this?
God: Is this some kind of math problem?
