They Could Not Believe
They Could Not Believe - 8A - Isaiah 6:8-10 & John 12:37-43
The Fulfillment
John 12:37-43 (RSV2CE)Though he had done so many signs before them, yet they did not believe in him; it was that the word spoken by the prophet Isaiah might be fulfilled: “Lord, who has believed our report, and to whom has the arm of the Lord been revealed?” Therefore, they could not believe. For Isaiah again said, “He has blinded their eyes and hardened their heart, lest they should see with their eyes and perceive with their heart, and turn for me to heal them.” Isaiah said this because he saw his glory and spoke of him. Nevertheless, many even of the authorities believed in him, but for fear of the Pharisees they did not confess it, lest they should be put out of the synagogue: for they loved the praise of men more than the praise of God.
The Prophecy
Isaiah 6:8-10 (RSV2CE)And I heard the voice of the Lord saying, “Whom shall I send, and who will go for us?” Then I said, “Here am I! Send me.” And he said, “Go, and say to this people: ‘Hear and hear, but do not understand; see and see, but do not perceive.’ Make the heart of this people fat, and their ears heavy, and shut their eyes; lest they see with their eyes and hear with their ears, and understand with their hearts, and turn and be healed.”
Significance of the Pairing
Isaiah’s commission reveals the sorrowful mystery of a people who hear God’s word yet resist its healing truth. John explicitly applies Isaiah’s words to the unbelief surrounding Jesus and declares that Isaiah saw His glory. The pairing unveils both Christ’s divine glory and the danger of preferring human approval to an open confession of faith; it calls us to receive God’s grace with hearts willing to turn and be healed.
