John Gill's Exposition of the Whole Bible
Isaiah 62:12
And they shall call them the holy people,.... For whom the way is prepared, to whom the standard is lifted up, and the proclamation made, and who upon it are gathered in to Christ the Saviour, and to the church: these shall be called, by men that know them, have a spirit of discerning, and are capable of judging, "the holy people"; a people separated and set apart for God, for his service and glory; chosen to be a special people, above all the people of the earth; chosen through sanctification of the Spirit, and to holiness here and hereafter, and so sanctified by God the Father, as in Judges 1:1, and in consequence of it are made holy by the Spirit of God, in the effectual calling; they are not holy by nature, nor by their own power, but by the grace of God, who calls them with a holy calling, and to holiness, and implants principles of grace and holiness in them, so that they are truly and really so. This character respects the church and its members in the latter day, when everyone that remains in Jerusalem, and every pot and vessel there, shall be holiness to the Lord; yea, that shall be upon the bells of the horses, Isaiah 4:3:
the redeemed of the Lord; which character includes the blessing of redemption, from whence the denomination is, which is a blessing of a spiritual nature; the redemption of the soul from sin, Satan, the law, its curse, and condemnation, and from all enemies; a blessing early in the heart of God; contrived by his infinite wisdom; secured in the covenant of grace; wrought out by Christ; is a plenteous one, containing various blessings of grace in it, and, in its effects and consequences, of an eternal duration: this character is also expressive of Christ, as the author of the above blessing: these are not redeemed by themselves, nor by their friends, nor by men, nor by angels, but by the Lord; who, as man, is the near kinsman of his people, and has the right to redeem; as God, he is mighty and able to redeem them; and who by his precious blood has obtained redemption for them; so that he has a property in them, which is asserted in this character; they are not their own, nor any other's but his, a peculiar people, redeemed from among men, the special favourites of heaven; and who, in consequence of it, are called, and kept, and saved with an everlasting salvation:
and thou shalt be called, Sought out; thou, daughter of Zion; or the church of God, consisting of elect, redeemed, and called ones; such as are sought out of the ruins of the fall, among the men of the world, and dust of the earth; found in a very miserable condition, usually by means of the Gospel, and by Christ, who knows them well, where are, and what the time of finding them, and can by name, and does; all which is the fruit and effect of his love unto them; though this character may chiefly respect the notice that will be taken of the church in the latter day; whereas she has been Zion, whom no man seeks after,
Jeremiah 30:17, now she shall be sought and flocked unto by all nations, and by great personages, even by the kings and princes of the earth, Isaiah 2:2.
A city not forsaken; the city of the living God, of which saints are fellow citizens, consisting of many persons, in good and flourishing circumstances, and which shall not be forsaken of men, as it has been,
Isaiah 60:15, but shall be filled with converts, both Jews and Gentiles; nor forsaken of God, but shall enjoy his gracious presence, and sensible communion with him in his ordinances; nor shall any of its true members be forsaken, or the work of grace in them; they shall none of them perish, but have everlasting life; so that here is a cluster of glorious doctrines, in their order and connection one with another: election in the first character; redemption in the second; effectual calling in the third; and final perseverance in the last.
