Revelation 3:12

“He that overcometh, etc.] 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…”

“pillar in the temple--In one sense there shall be "no temple" in the heavenly city because there shall be no distinction of things into sacred and secular, for all things and persons shall be holy to the Lord. The city shall be all one great temple, in which the saints shall be not merely stones, as m the spiritual temple now on earth, but all eminent as pillars: immovably firm (unlike Philadelphia, the city which was so often shaken by earthquakes, STRABO [12 and 13]), like the colossal pillars before Solomon's temple, Boaz (that is, "In it is strength") and Jachin ("It shall be established"): only that those pillars were outside, these shall be within the temple. my God--(See on Rev 2:7).…”

“Him that overcometh - See the notes on Revelation 2:7. Will make a pillar in the temple of my God - See the introductory remarks to this epistle. The promised reward of faithfulness here is, that he who was victorious would be honored as if he were a pillar or column in the temple of God. Such a pillar or column was partly for ornament, and partly for support; and the idea here is, that in that temple he would contribute to its beauty and the justness of its proportions, and would see the same time be honored as if he were a pillar which was necessary for the support of the temple. It is not uncommon in the New Testament to represent the church as a temple, and Christians as parts of it. See…”

“I will make him a pillar in the temple of my God - I will fix him as beautiful, as useful, and as immovable as a pillar in the church of God. And he shall go out no more - But shall be holy and happy for ever. And I will write upon him the name of my God - So that the nature and image of God shall appear visibly upon him. And the name of the city of my God - Giving him a title to dwell in the New Jerusalem. And my new name - A share in that joy which I entered into, after overcoming all my enemies. Revelation 3:14”

“3:12 Victorious Christians are secure in God’s household since, like pillars, . . . they will never have to leave it. • The name of . . . God that is inscribed on them portrays God’s ownership and the security Christians thus enjoy (see 7:4; 14:1). • The new Jerusalem is not a realm constructed by humans, but is God’s gift from heaven (21:2-10). • A new name was a sign of God’s blessing (see also 2:17); Abram, Jacob, Simon, and others were given new names (Gen 17:5; 32:28; John 1:42).”
