Show me a sign! (Luke 11:29-36)

How does Jesus respond when people demand a sign from him?

Does God give us signs today?

29 As the crowds were increasing, he began saying: “This generation is an evil generation. It demands a sign, but no sign will be given to it except the sign of Jonah.[fn] 30 For just as Jonah became a sign to the people of Nineveh, so also the Son of Man will be to this generation. 31 The queen of the south will rise up at the judgment with the men of this generation and condemn them, because she came from the ends of the earth to hear the wisdom of Solomon, and look ​— ​something greater than Solomon is here. 32 The men of Nineveh will stand up at the judgment with this generation and condemn it, because they repented at Jonah’s preaching, and look ​— ​something greater than Jonah is here.

33 “No one lights a lamp and puts it in the cellar or under a basket,[fn] but on a lampstand, so that those who come in may see its light. 34 Your eye is the lamp of the body. When your eye is healthy, your whole body is also full of light. But when it is bad, your body is also full of darkness. 35 Take care, then, that the light in you is not darkness. 36 If, therefore, your whole body is full of light, with no part of it in darkness, it will be entirely illuminated, as when a lamp shines its light on you.”
