35 Jesus said to them, For a little time longer the light will be among you; while you have the light go on walking in it, so that the dark may not overtake you: one walking in the dark has no knowledge of where he is going. 36 In so far as you have the light, put your faith in the light so that you may become sons of light. With these words Jesus went away and for a time was not seen again by them.

Commentary on John 12:34-36
(Read John 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.
