Revelation 3:12

He that overcometh,.... In the hour of temptation, in this period of time; that stands his ground then, sustains the shock of the beast, with courage and intrepidity, and overcomes him:

will I make a pillar in the temple of my God; by which is meant not the church triumphant, though such will have a place, and an abiding one there; but the church militant, so called in allusion to the temple at Jerusalem, for its author, matter, situation, strength, solidity, magnificence, and stateliness, and for its holiness; and may be said to be the temple of God, because it is of his building, and is the place where he dwells, and is worshipped; and the temple of Christ's God, as he is man and Mediator, through whom all worship is given to God in it; and those who are overcomers by the grace and strength of Christ are made pillars by him here, in allusion to the two pillars, Jachin and Boaz, in Solomon's temple; that is, they become very ornamental in the church, they are made honourable members of it; they come in at the right door into it, and fill up their places, and all relative duties in it, and walk becoming their profession; and, like pillars, are a support to it, to the interest of the church, the truths of the Gospel, and to weak and poor saints; and, as pillars, they are upright in heart and conversation, and are steady, firm, and constant:

and he shall go no more out; out of the church, the temple of the Lord, but shall abide in it unto death: it is a promise of perseverance both in the grace of God, and in a profession of religion; there shall not be such instances of apostasy as now.

And I will write upon him the name of my God; in allusion to inscriptions of names on pillars; the sense is, that it should be manifest that such are interested in God, as their covenant God and Father, in like manner as he is the God and Father of Christ; and this should be as plain and as evident as an inscription on a pillar, or as if it was written upon their foreheads, as the high priest had on his forehead written, "holiness to the Lord"; and indeed it will be by their holiness that it will so clearly appear that God is their covenant God; for in this church state, or spiritual reign of Christ, holiness unto the Lord shall be upon the bells of the horses:

and the name of the city of my God; [which is] new Jerusalem, in allusion to "Jehovah Shammah"; meaning the Gospel church in the latter day glory; and the sense is, that such shall be manifestly citizens of this city, in this new and glorious state of the church, and shall enjoy all the privileges of it, which at this time especially will be many and great. This will not be the new Jerusalem church state, or the thousand years' reign of Christ in person, for in that there will be no temple, as in this; but it will have the name, and some appearance of it; it will bear some resemblance to it, and be a pledge of it:

which cometh down out of heaven, from my God; as it is before called new Jerusalem, in distinction from the old, so here it is said to come down from heaven, or to be the heavenly Jerusalem, in distinction from the earthly one. The inhabitants of it will be born from above, and be called with an heavenly calling, and their conversation will be in heaven, and all the glory of this church will come from God.

And [I will write upon him] my new name; either the name of "Jehovah" our righteousness; or rather the name of King of kings, and Lord of lords, Revelation 19:16; which Christ will now acquire, or at least this will now be made more manifest upon the destruction of antichrist, in this church state; in which conquest he will make all his people sharers, and they shall now more openly appear to be kings, and to reign with him in his spiritual kingdom.
