Revelation 3:11-13

I come quickly: hold fast that which thou hast, that no one take thy crown. He that overcometh, I will make him a pillar in the temple of my God, and he shall go out thence no more: and I will write upon him the name of my God, and the name of the city of my God, the new Jerusalem, which cometh down out of heaven from my God, and mine own new name. He that hath an ear, let him hear what the Spirit saith to the churches.
