Revelation 3:10-12

Because you have kept my command to endure, I will also keep you from the hour of testing that is going to come on the whole world to test those who live on the earth. I am coming soon. Hold on to what you have, so that no one takes your crown. “The one who conquers I will make a pillar in the temple of my God, and he will never go out again. I will write on him the name of my God and the name of the city of my God — the new Jerusalem, which comes down out of heaven from my God — and my new name.
