29 And the multitudes crowding together upon him, he began to say, 'This generation is evil, a sign it doth seek after, and a sign shall not be given to it, except the sign of Jonah the prophet, 30 for as Jonah became a sign to the Ninevites, so also shall the Son of Man be to this generation. 31 'A queen of the south shall rise up in the judgment with the men of this generation, and shall condemn them, because she came from the ends of the earth to hear the wisdom of Solomon; and lo, greater than Solomon here! 32 'Men of Nineveh shall stand up in the judgment with this generation, and shall condemn it, because they reformed at the proclamation of Jonah; and lo, greater than Jonah here!
33 'And no one having lighted a lamp, doth put 'it' in a secret place, nor under the measure, but on the lamp-stand, that those coming in may behold the light. 34 'The lamp of the body is the eye, when then thine eye may be simple, thy whole body also is lightened; and when it may be evil, thy body also is darkened; 35 take heed, then, lest the light that 'is' in thee be darkness; 36 if then thy whole body is lightened, not having any part darkened, the whole shall be lightened, as when the lamp by the brightness may give thee 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.
