John 12:38-41

38 In this way the words of the prophet Isaiah came true: "Lord, who has believed our message? To whom has the Lord's power been revealed?"

39 So the people couldn't believe because, as Isaiah also said,

40 "God blinded them and made them close-minded so that their eyes don't see and their minds don't understand. And they never turn to me for healing!"

41 Isaiah said this because he had seen Jesus' glory and had spoken about him.
