John 12:35-40

Jesus replied, “You will have the light shining with you for only a little while longer. While you still have me, walk in the light, so that the darkness doesn’t overtake you. For when you walk in the dark you have no idea where you’re going. So believe and cling to the light while I am with you, so that you will become children of light.” After saying this, Jesus then entered into the crowd and hid himself from them. Even with the overwhelming evidence of all the many signs and wonders that Jesus had performed in front of them, his critics still refused to believe. This fulfilled the prophecy given by Isaiah: Lord, who has believed our message? Who has seen the unveiling of your great power? And the people were not able to believe, for Isaiah also prophesied: God has blinded their eyes and hardened their hearts to the truth. So with their eyes and hearts closed they cannot understand the truth nor turn to me so that I could instantly cleanse and heal them.
