John 12:37-41

37Although Jesus had performed so many miraculous signs before them, they still refused to believe in him,

38so that the word of Isaiah the prophet would be fulfilled. He said, “Lord, who has believed our message, and to whom has the arm of the Lord been revealed?”

39For this reason they could not believe, because again Isaiah said,

40“He has blinded their eyes and hardened their heart, so that they would not see with their eyes and understand with their heart, and turn to me, and I would heal them.”

41Isaiah said these things because he saw Christ’s glory, and spoke about him.
