Revelation 3:11-12

11I come quickly: hold fast what thou hast, that no one take thy crown.

12He that overcomes, him will I make a pillar in the temple of my 1God, and he shall go no more at all out; and I will write upon him the name of my 2God, and the name of the city of my 3God, the new Jerusalem, which comes down out of heaven, from my 4God, and my new name.
