John 12:39

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

John 12:39 Meaning and Commentary

John 12:39

Therefore they could not believe
God had determined to leave them to the blindness and hardness of their hearts, and to deny them his grace, which only could cure them of it, and enable them to believe: he had foretold this in prophecy, and they were manifestly the persons spoken of; and therefore considering the decrees of God, the predictions of the prophet, and the hardness of their hearts, they were left unto, it was morally impossible they should believe,

because that Esaias said again,
in ( Isaiah 6:9 Isaiah 6:10 ) .

John 12:39 In-Context

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

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

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 be converted, and I would heal them.

41 Isaiah said these things because he saw His glory and spoke about Him.
