Revelation 3

11 Behold, I come quickly, be holding fast that which you have, that no one may receive your garland. 12 He who is overcoming—I will make him a pillar in the temple of My God, and he may not go outside anymore, and I will write on him the Name of My God, and the name of the city of My God, the New Jerusalem, that comes down out of Heaven from My God—also My new Name.
