Verses 25-29: "As He saith also in Hosea, I will call them my people, which were not my people; and her beloved, which was not beloved. And it shall come to pass, that in the place where it was said unto them, Ye are not my people; there shall they be called the children of the living God. Isaiah also crieth concerning Israel, Though the number of the children of Israel be as the sand of the sea, a remnant shall be saved: For He will finish the work, and cut it short in righteousness: because a short work will the Lord make upon the earth.

Hosea's prophecy is being fulfilled today in this wonderful day of grace.
Paul asks another question in verses 30-33: "What shall we say then? That the Gentiles, which followed not after righteousness, have attained to righteousness, even the righteousness which is of faith. But Israel, which followed after the law of righteousness, hath not attained to the law of righteousness. Wherefore? Because they sought it not by faith, but as it were by the works of the law. For they stumbled at that stumb
