Luke 11:15
The sign of Jonah is the only sign this evil generation will receive: as Jonah was a sign to the Ninevites, so will the Son of Man be a sign to this generation. The Ninevites repented at Jonah's preaching, and the Queen of the South came from the ends of the earth to hear Solomon's wisdom — and something greater than both Jonah and Solomon is here, standing before a generation that refuses to repent.
