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.
For those who overcome, I will turn them into pillars in God's temple and they won't leave. I will write the names of my God, the city of my God (new Jerusalem), and my new name on them. This is all because the new Jerusalem comes down from heaven, sent by God.
