I will sow her to me in the earth; And I will have mercy on her who had not obtained mercy; And I will tell those who were not my people, 'You are my people;' And they will say, 'My God!'"
I will ... have mercy upon her that had not obtained mercy - This which was true of Israel in its dispersion, was much more true of the Gentiles. These too, the descendants of righteous Noah, God had cast off for the time, that they should be no more His people, when he chose Israel out of them, to make known to them His Being, and His will, and His laws, and, (although in shadow and in mystery,) Christ who was to come. So God’s mercies again overflow His threatenings. He had threatened to Israel, that he should be “unpitied,” and no more His people; in reversing His sentence, He embraces in the arms of His mercy all who were not His people, and says of them all, that they should be “My people and beloved.” At one and the same time, was Israel to be thus multiplied, and “pity” was to be shown to those not pitied, and those who were “not God’s people,” were to become “His people.” At one and the same time were those promises fulfilled in Christ; the one through the other; Israel was not multiplied by itself; but through the bringing in of the Gentiles. Nor was Israel alone, or chiefly, brought into a new relation with God. The same words promised the same mercy to both, Jew and Gentile, that all should be “one in Christ,” all one Jezreel, one Spouse to Himself, one Israel of God, one Beloved; and that all, with one voice of jubilee. should cry unto Him, “my Lord and my God.”
