The Gospel According to Hosea and Isaiah

"Having explained the promise, and proved the divine sovereignty, the apostle here shows how the rejection of the Jews, and the taking in of the Gentiles, were foretold in the Old Testament, and therefore must needs be very well consistent with the promise made to the fathers under the Old Testament. It tends very much to the clearing of a truth to observe how the scripture is fulfilled in it. The Jews would, no doubt, willingly refer it to the Old Testament, the scriptures of which were committed to them. Now he shows how this, which was so uneasy to them, was there spoken of…. The Gentiles had not been the people of God, not owning him, nor being owned by him in that relation: "But," says he, "I will call them my people, make them such and own them as such, notwithstanding all their unworthiness." A blessed change! Former badness is no bar to God's present grace and mercy. - And her beloved which was not beloved. Those whom God calls his people he calls beloved: he loves those that are his own…. Behold, what manner of love! This honor have all his saints." – Matthew Henry
