33 But no one having lit a lamp sets it in secret, nor under the corn-measure, but on the lamp-stand, that they who enter in may see the light. 34 The lamp of the body is thine eye: when thine eye is simple, thy whole body also is light; but when it is wicked, thy body also is dark. 35 See therefore that the light which is in thee be not darkness. 36 If therefore thy whole body [is] light, not having any part dark, it shall be all light as when the lamp lights thee with its brightness.
Matthew Henry's Commentary on Luke 11:33-36
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.
