34The people answered Him: “We have heard from the Law that the Messiah remains forever; and so how can you say, ‘The Son of the Man must be lifted up’? Who is this ‘the Son of the Man’?”
35Then Jesus said to them: “The Light will be with you just a little longer. Walk while you have the light, so that darkness does not overtake you; the one who walks in the darkness does not know where he is going.
36While you have the Light, believe into the Light, so that you may become sons of light.” Jesus said these things, and going away He was hidden from them.
37Although He had performed so many signs in their presence, they were not believing into Him;
38so that the word spoken by Isaiah the prophet should be fulfilled: “Lord, who has believed what we heard? And to whom has the arm of the Lord really been revealed?”
39Therefore they were unable to believe, in that Isaiah said again:
40“He has blinded their eyes and hardened their hearts, lest they should see with their eyes and understand with their hearts and should turn around, and I would heal them.”
41Isaiah said these things when he saw His glory and spoke concerning Him.
42Nevertheless, even among the rulers many believed into Him, but because of the Pharisees they did not confess Him, so they would not be expelled from the synagogue;
43for they loved the praise of men more than the praise of God.
44Jesus called out and said: “The one believing into me believes not into me but into Him who sent me.
45And the one seeing me sees Him who sent me.
46I, Light, have come into the world so that everyone who believes into me will not remain in the darkness.
