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.
37 But though he had done such a number of signs before them, they still had no belief in him:
38 So that the words of the prophet Isaiah might come true, when he said, Lord, who has any belief in our preaching? and the arm of the Lord, to whom has it been unveiled?
39 For this reason they were unable to have belief, because Isaiah said again,
40 He has made their eyes blind, and their hearts hard; for fear that they might see with their eyes and get knowledge with their hearts, and be changed, and I might make them well.
41 (Isaiah said these words because he saw his glory. His words were about him.)
