One shall say, I am the Lord's,.... This expresses the success of the apostles' ministry, not only among the Jews, but more especially among the Gentiles, who were not called by the name of Jacob and Israel; but now should call themselves by those names, as the following clauses show, being called by grace and converted; when they should openly profess their faith in Christ, claim their interest in him, and acknowledge his property in them, and not be ashamed of the name of Christians; and this one, and another, even many should do.
The Lord has a people who are his special and peculiar people, his beloved ones, the objects of his delight and pleasure, his chosen and covenant ones, his adopted ones, his treasure and his jewels; and hence he has taken such care of them; he has put them into the hands of Christ for their security; given him to be a Head, Redeemer, and Saviour of them; bestows every blessing of grace on them; will not suffer any to hurt them; and keeps them by his power: and having given them to Christ, they are his people, his portion, his spouse and bride, his children, and the sheep of his hand; hence he became incarnate on their account; laid down his life to save them; sends his Gospel, and along with it his Spirit effectually to call them; and hence all that he has is theirs, and he will keep them, and not lose any of them: and being called by grace, they are the workmanship of the Spirit; his temples in which he dwells, and in whom he is as the earnest and pledge of their eternal glory: and this interest the Lord has in his people may be known by them, so as that they may be able to say, one and another, "I am the Lord's", as many of them have done; see Ps 119:94, they may know they are the Lord's beloved ones, by his drawing them with his love, by the communications of his grace to them, by the communion with himself he indulges them with, and by what he shows unto them, and by the shedding abroad of his love in them; and that they are his chosen ones, by the Gospel coming in power to them, by their effectual calling, by the sanctification of the Spirit, and their faith in Christ Jesus; and that they are his covenant ones, by the application of covenant grace and blessings to them; and that they are his adopted ones, by the Spirit of adoption sent down into their hearts, witnessing it unto them; they may know that they are the redeemed of the Lamb, by their having his Spirit, and by his being formed in their hearts: and they may know that they are the temples of the Holy Ghost, by his own work upon them, and his dwelling in them: and knowing this, they should and will declare, and say they are the Lord's and none other's; that they are not their own, nor Satan's, nor the servants of men, but the Lord's to whom they devote themselves, and whom they desire to serve; and therefore join themselves to his churches, and walk in his ordinances, publicly confessing their faith in him, which is telling all the world whose they are; and this they say with the utmost joy and pleasure, in an exulting, yea, even boasting way and manner.
The Targum is,"this shall say, I am of them that fear the Lord:''and another shall call himself by the name of Jacob; reckon himself of the posterity of Jacob, in a spiritual sense; count it an honour to be called a wrestling Jacob, and a prevailing Israelite; so the Targum,"this shall pray in the name of Jacob;''either in the name of the God of Jacob, the Messiah, or as Jacob did: "and another shall subscribe with his hand to the Lord": shall give his hand and seal to serve the Lord; shall esteem it his high and great privilege to be written among the living in Jerusalem and to have his name registered among the saints, and in their church book.
The Targum is,"and this shall offer his oblation before the Lord;''himself and his sacrifices of prayer and praise: "and surname himself by the name of Israel": shall value himself upon this, that he is an Israelite indeed, and shall choose no other name to be called by than that of a Christian.
