John 12:36-41

Believe in the light while you still have it so that you will become children of light.” When Jesus had said this, he left and hid himself from them. Though Jesus had done many miracles in front of the people, they still did not believe in him. This was to bring about what Isaiah the prophet had said: “Lord, who believed what we told them? Who saw the Lord’s power in this?” This is why the people could not believe: Isaiah also had said, “He has blinded their eyes, and he has closed their minds. Otherwise they would see with their eyes and understand in their minds and come back to me and be healed.” Isaiah said this because he saw Jesus’ glory and spoke about him.
