||Illustration of John 12:37-41 NLT -- But despite all the miraculous signs Jesus had done, most of the people still did not believe in him. This is exactly what Isaiah the prophet had predicted: "Lord, who has believed our message? To whom has the Lord revealed his powerful arm?" But the people couldn't believe, for as Isaiah also said, "The Lord has blinded their eyes and hardened their hearts — so that their eyes cannot see, and their hearts cannot understand, and they cannot turn to me and have me heal them." Isaiah was referring to Jesus when he said this, because he saw the future and spoke of the Messiah's glory.
