38 Later a few religion scholars and Pharisees got on him. "Teacher, we want to see your credentials. Give us some hard evidence that God is in this. How about a miracle?" 39 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. 40 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. 41 "On Judgment Day, the Ninevites will stand up and give evidence that will condemn this generation, because when Jonah preached to them they changed their lives. A far greater preacher than Jonah is here, and you squabble about 'proofs.' 42 On Judgment Day, the Queen of Sheba will come forward and bring evidence that will condemn this generation, because she traveled from a far corner of the earth to listen to wise Solomon. Wisdom far greater than Solomon's is right in front of you, and you quibble over 'evidence.'
43 "When a defiling evil spirit is expelled from someone, it drifts along through the desert looking for an oasis, some unsuspecting soul it can bedevil. When it doesn't find anyone, 44 it says, 'I'll go back to my old haunt.' On return it finds the person spotlessly clean, but vacant. 45 It then runs out and rounds up seven other spirits more evil than itself and they all move in, whooping it up. That person ends up far worse off than if he'd never gotten cleaned up in the first place. "That's what this generation is like: You may think you have cleaned out the junk from your lives and gotten ready for God, but you weren't hospitable to my kingdom message, and now all the devils are moving back in."

Commentary on Matthew 12:38-45
(Read Matthew 12:38-45)
Though Christ is always ready to hear and answer holy desires and prayers, yet those who ask amiss, ask and have not. Signs were granted to those who desired them to confirm their faith, as Abraham and Gideon; but denied to those who demanded them to excuse their unbelief. The resurrection of Christ from the dead by his own power, called here the sign of the prophet Jonah, was the great proof of Christ's being the Messiah. As Jonah was three days and three nights in the whale, and then came out again alive, thus Christ would be so long in the grave, and then rise again. The Ninevites would shame the Jews for not repenting; the queen of Sheba, for not believing in Christ. And we have no such cares to hinder us, we come not to Christ upon such uncertainties. This parable represents the case of the Jewish church and nation. It is also applicable to all those who hear the word of God, and are in part reformed, but not truly converted. The unclean spirit leaves for a time, but when he returns, he finds Christ is not there to shut him out; the heart is swept by outward reformation, but garnished by preparation to comply with evil suggestions, and the man becomes a more decided enemy of the truth. Every heart is the residence of unclean spirits, except those which are temples of the Holy Ghost, by faith in Christ.
