Later a few religion scholars and Pharisees cornered him. “Teacher, we want to see your credentials. Give us some hard evidence that God is in this. How about a miracle?” Jesus said, “You’re looking for proof, but you’re looking for the wrong kind. All you want is something to titillate your curiosity, satisfy your lust for miracles. The only proof you’re going to get is what looks like the absence of proof: Jonah-evidence. Like Jonah, three days and nights in the fish’s belly, the Son of Man will be gone three days and nights in a deep grave.
