John 12:35-40

35Jesus answered, ‘The light will be with you for only a short time longer. So continue to walk while you still have the light. Do that, so that the dark will not come over you. Anyone who walks in the dark does not know where they are going.

36While you still have the light with you, believe in that light. So then you will become children of light.’ When Jesus had said this, he went away. He hid himself from them.

37Jesus had done many miracles that the people themselves had seen. But even then, they still did not believe in him.

38This showed that the prophet Isaiah had spoken true words when he said: ‘Lord, has anyone believed our message? You have shown how powerful you are, but nobody has really understood.’

39Isaiah spoke also about why the people could not believe.

40He said: ‘God has made their eyes unable to see. He has closed their minds. So they cannot see with their eyes, and they cannot understand with their minds. They will not turn to me, so that I can make them well.’
