John 12:36-41

36While you have the light, believe in the light, that you may become sons of light.” These things Jesus spoke, and departed, and was hidden from them.

37But although He had done so many signs before them, they did not believe in Him,

38that the word of Isaiah the prophet might be fulfilled, which he spoke: “Lord, who has believed our report? And to whom has the arm of the Lord been revealed?”

39Therefore they could not believe, because Isaiah said again:

40“He has blinded their eyes and hardened their hearts, Lest they should see with their eyes, Lest they should understand with their hearts and turn, So that I should heal them.”

41These things Isaiah said when he saw His glory and spoke of Him.
