John 12 on the bad will of men

John 12:37-40 “Although Jesus had performed so many signs in their presence, they still did not believe in Him. This was to fulfill the word of Isaiah the prophet: ‘Lord, who has believed our message? And to whom has the arm of the Lord been revealed?’ For this reason they were unable to believe. For again, Isaiah says: He has blinded their eyes and hardened their hearts, so that they cannot see with their eyes, and understand with their hearts, and turn, and I would heal them.”
