29 As the crowd pressed in on Jesus, he said, "This evil generation keeps asking me to show them a miraculous sign. But the only sign I will give them is the sign of Jonah. 30 What happened to him was a sign to the people of Nineveh that God had sent him. What happens to the Son of Man will be a sign to these people that he was sent by God. 31 "The queen of Sheba will stand up against this generation on judgment day and condemn it, for she came from a distant land to hear the wisdom of Solomon. Now someone greater than Solomon is here-but you refuse to listen. 32 The people of Nineveh will also stand up against this generation on judgment day and condemn it, for they repented of their sins at the preaching of Jonah. Now someone greater than Jonah is here-but you refuse to repent.
33 "No one lights a lamp and then hides it or puts it under a basket. Instead, a lamp is placed on a stand, where its light can be seen by all who enter the house. 34 "Your eye is a lamp that provides light for your body. When your eye is good, your whole body is filled with light. But when it is bad, your body is filled with darkness. 35 Make sure that the light you think you have is not actually darkness. 36 If you are filled with light, with no dark corners, then your whole life will be radiant, as though a floodlight were filling you with light."

Commentary on Luke 11:29-36
(Read Luke 11:29-36)
Christ promised that there should be one sign more given, even the sign of Jonah the prophet; which in Matthew is explained, as meaning the resurrection of Christ; and he warned them to improve this sign. But though Christ himself were the constant preacher in any congregation, and worked miracles daily among them, yet unless his grace humbled their hearts, they would not profit by his word. Let us not desire more evidence and fuller teaching than the Lord is pleased to afford us. We should pray without ceasing that our hearts and understandings may be opened, that we may profit by the light we enjoy. And especially take heed that the light which is in us be not darkness; for if our leading principles be wrong, our judgment and practice must become more so.
