29 When the multitudes were gathering together to him, Jesus began to say, “This is an evil generation. It seeks after a sign. No sign will be given to it but the sign of Jonah, the prophet. 30 For even as Jonah became a sign to the Ninevites, so will also the Son of Man be to this generation. 31 The Queen of the South will rise up in the judgment with the men of this generation, and will condemn them: for she came from the ends of the earth to hear the wisdom of Solomon; and behold, one greater than Solomon is here. 32 The men of Nineveh will stand up in the judgment with this generation, and will condemn it: for they repented at the preaching of Jonah, and behold, one greater than Jonah is here."

Luke 11:29-32 - World English Bible

In Luke 11, Jesus addressed an evil generation that sought a sign, a people that do not look to God but toward an event, a show of power, that would wow them. He said the sign would be preaching repentance, just as Jonah did among the Ninevites. The Queen of the South (a ruler from the coast of the Red Sea around Yemen or Ethiopia; 1 Kings 10:1-13) who brought tribute to Solomon for his wisdom would rise to condemn the present culture for its lack of that virtue. The Ninevites themselves would stand up to judge the evil ones for their lack of repentance. Notice the explicit and implicit themes. The "one greater than Jonah" was the Christ (and, by extension, the one who preached the Good News just as the Lord did); the content of the message was the Good News, repentance with a view to the coming Kingdom. In his judgment on the evil generation, Jesus implied resurrection; the Queen of the South would rise to condemn, the Ninevites would "stand up" (another code phrase for resurrection) to judge. In the context of the gospel, the Lord chided his listeners for their failure to listen with two images: the sign of Jonah and the rising of biblical figures to damn the unbelievers at the Last Judgment.

How have "listened" to the Good News today?
