John 12:37-43

37Even though he had performed so many signs in their presence, they did not believe in him.

38This was to fulfill the word of Isaiah the prophet, who said: Lord, who has believed our message? And to whom has the arm of the Lord been revealed?

39This is why they were unable to believe, because Isaiah also said:

40He has blinded their eyes and hardened their hearts, so that they would not see with their eyes or understand with their hearts, and turn, and I would heal them.

41Isaiah said these things because he saw his glory and spoke about him.

42Nevertheless, many did believe in him even among the rulers, but because of the Pharisees they did not confess him, so that they would not be banned from the synagogue.

43For they loved human praise more than praise from God.
