II. That that kingdom shall be enlarged, and the territories of it shall extend far, by the accession of many countries to it (v. 12), that the house of David may possess the remnant of Edom, and of all the heathen, that is, that Christ may have them given him for his inheritance, even the uttermost parts of the earth for his possession, Ps. ii. 8. Those that had been strangers and enemies shall become willing faithful subjects to the Son of David, shall be added to the church, or those of them that are called by my name, saith the Lord, that is, that belong to the election of grace and are ordained to eternal life (Acts xiii. 48), for it is true of the Gentiles as well as of the Jews that the election hath obtained and the rest were blinded, Rom. xi. 7. Christ died to gather together in one the children of God that were scattered abroad, here said to be those that were called by his name. The promise is to all that are afar off, even as many of them as the Lord our God shall call, Acts ii. 39. St. James expounds this as a promise that the residue of men should seek after the Lord, even all the Gentiles upon whom my name is called. But may the promise be depended upon? Yes, the Lord says this, who does this, who can do it, who has determined to do it, the power of whose grace is engaged for the doing of it, and with whom saying and doing are not two things, as they are with us.
