Yet the number of the children of Israel will be as the sand of the sea, which can't be measured nor numbered; and it will come to pass that, in the place where it was said to them, 'You are not my people,' they will be called 'sons of the living God.'
And it shall be in the place where it had been said, Ye are not my people; there it shall be said, Ye are the sons of the living God The Prophet, in these words, amplifies by a comparison the grace of God; as though he said, “When God shall restore anew his Church, its state shall be more excellent than before.” How so? “They shall not only,” he says, “be the people of God, but also the sons of the living God;” which means, that God will more familiarly show himself a Father to those, whom he will thus suddenly gather into one body. I indeed allow that the ancients under the law were honoured with this title; but we ought to attend to the present passage; for the Prophet contrasts the two clauses, the one with the other: And it shall be in the place where it had been said, Ye are not my people; it shall be said there, Ye are the sons of the living God He might have said, “And it shall be in the place where it had been said, Ye are not my people; there it shall be said, Ye are not my people:” but he ascends higher; God will confer more honour on his new people, for he will more clearly manifest his favour to them by this title of adoption: and it belongs in common to all, to the Gentiles as well as to the Israelites. We ought not to apply this, as it is commonly done, exclusively to the Gentiles: for Hosea speaks not here only of the Church which God attained for himself from the Gentiles, but of the whole Israel of God, a part of whom is the seed of Abraham. Let us then know that God here offers his grace generally, to the Israelites as well as to the Gentiles, and testifies, that after having justly cast away this people, he would make all to know that he had not been unmindful of his covenant, for he would attain to himself a much larger Church — from whom? From the children of Abraham, as it has been said, as well as from strangers.
