12:34-36 The people drew false notions from the Scriptures, because they overlooked the prophecies that spoke of Christ's sufferings and death. Our Lord warned them that the light would not long continue with them, and exhorted them to walk in it, before the darkness overtook them. Those who would walk in the light must believe in it, and follow Christ's directions. But those who have not faith, cannot behold what is set forth in Jesus, lifted up on the cross, and must be strangers to its influence as made known by the Holy Spirit; they find a thousand objections to excuse their unbelief.

35, 36. Yet a little while is the light with you. Walk while ye have the light, &c.—Instead of answering their question, He warns them, with mingled majesty and tenderness, against trifling with their last brief opportunity, and entreats them to let in the Light while they have it in the midst of them, that they themselves might be "light in the Lord." In this case, all the clouds which hung around His Person and Mission would speedily be dispelled, while if they continued to hate the light, bootless were all His answers to their merely speculative or captious questions. (See on [1841]Lu 13:23).
