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 But as many signs [as] he had performed before them, they did not believe in him,

38 in order that the word of the prophet Isaiah would be fulfilled, who said, "Lord, who has believed our message? And to whom has the arm of the Lord been revealed?"

39 For this [reason] they were not able to believe, because again Isaiah said,

40 "He has blinded their eyes and hardened their hearts, lest they see with [their] eyes and understand with [their] hearts and turn, and I heal them."

41 Isaiah said these [things] because he saw his glory, and he spoke about him.
