Romans 10:16

Who has believed our report? And to whom has the arm of Yahweh been revealed?

“And in them the prophecy of Isaiah is being fulfilled, which says, ‘You will keep on hearing, but will not understand; You will keep on seeing, but will not perceive;

so that the word of Isaiah the prophet might be fulfilled, which he spoke: “Lord, who has believed our report? And to whom has the arm of the Lord been revealed?”

What then? If some did not believe, does their unbelief abolish the faithfulness of God?
