John 12:36-41

While you have the Light, believe in the Light, so that you may become sons of Light.” T hese things Jesus spoke, and He went away and hid Himself from them. But though He had performed so many signs before them, yet they were not believing in Him. This was to fulfill the word of Isaiah the prophet which he spoke: “LORD, WHO HAS BELIEVED OUR REPORT? AND TO WHOM HAS THE ARM OF THE LORD BEEN REVEALED?” For this reason they could not believe, for Isaiah said again, “HE HAS BLINDED THEIR EYES AND HE HARDENED THEIR HEART, SO THAT THEY WOULD NOT SEE WITH THEIR EYES AND PERCEIVE WITH THEIR HEART, AND BE CONVERTED AND I HEAL THEM.” These things Isaiah said because he saw His glory, and he spoke of Him.
