35 Then Jesus told them, "You are going to have the light just a little while longer. Walk while you have the light. Do this before darkness catches up with you. Anyone who walks in the dark does not know where he is going.
36 While you have the light, put your trust in it. Then you can become sons of light." When Jesus had finished speaking, he left and hid from them.
37 Jesus had done all these miraculous signs in front of them. But they still would not believe in him.
38 This happened as Isaiah the prophet had said it would. He had said, "Lord, who has believed what we've been saying? Who has seen the Lord's saving power?" (Isaiah 53:1)
39 For this reason, they could not believe. As Isaiah says in another place,
40 "The Lord has blinded their eyes. He has closed their minds. So they can't see with their eyes. They can't understand with their minds. They can't turn to the Lord. If they could, he would heal them." (Isaiah 6:10)
41 Isaiah said this because he saw Jesus' glory and spoke about him.
