John 12:37-40 ▼

37 Even though he had performed so many signs in their presence, they did not believe in him.

38 This was to fulfill the word of Isaiah the prophet, who said: Lord, who has believed our message? And to whom has the arm of the Lord been revealed?

39 This is why they were unable to believe, because Isaiah also said:

40 He has blinded their eyes and hardened their hearts, so that they would not see with their eyes or understand with their hearts, and turn, and I would heal them.
