I will assume that the ingenious hoax and psychiatric disorder possibilities get completely ruled out. At that point, I would take advice as to whether some sort of malicious supernatural entity is attempting to deceive me. If I am absolutely persuaded it is God, the Christian God, well, denying him would be pretty -EV. Being only human (and especially prone to sympathy for the devil), I'd probably be pretty irritated.
