“Him that overcometh will I make a pillar in the temple of my God, and he shall go no more out: and I will write upon him the name of my God, and the name of the city of my God, which is new Jerusalem, which cometh down out of heaven from my God: and I will write upon him my new name.”
King James Version (KJV)
3:12 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.
Re 3:12 A pillar. A term implying strength, permanence and honor. In the temple of my God. Not in any material temple, but in the church, either on earth or in heaven. The latter is here meant. The New Jerusalem has no temple in it because it is all temple. He shall go no more out. Always dwell there. I will write upon him the name of my God. When one enters the church, the spiritual temple below, three names are recorded in his baptismal formula. When he enters the kingdom above, three names are again written upon him; the name of God, of the heavenly city, and Christ's heavenly name.
