Luke 11:29-36

²⁹Now as the crowds were increasing, He began to say, “This generation is a wicked generation; it demands a sign, and so no sign will be given to it except the sign of Jonah. ³⁰For just as Jonah became a sign to the Ninevites, so will the Son of Man be to this generation. ³¹The Queen of the South will rise up with the men of this generation at the judgment and condemn them, because she came from the ends of the earth to listen to the wisdom of Solomon; and behold, something greater than Solomon is here. ³²The men of Nineveh will stand up with this generation at the judgment and condemn it, because they repented at the preaching of Jonah; and behold, something greater than Jonah is here.

³³“No one lights a lamp and puts it away in a cellar nor under a basket, but on the lampstand, so that those who enter may see the light. ³⁴Your eye is the lamp of your body; when your eye is clear, your whole body also is full of light; but when it is bad, your body also is full of darkness. ³⁵So watch out that the light in you is not darkness. ³⁶Therefore if your whole body is full of light, without any dark part, it will be wholly illuminated, as when the lamp illuminates you with its light.”
