John 12:39-43

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. Isaiah said these things because he had seen and experienced the splendor of Jesus and prophesied about him. Yet there were many Jewish leaders who believed in Jesus, but because they feared the Pharisees they kept it secret, so they wouldn’t be ostracized by the assembly of the Jews. For they loved the glory that men could give them rather than the glory that came from God!
