Revelation 3:11-13

But I come swiftly, so cling tightly to what you have, so that no one may seize your crown of victory. For the one who is victorious, I will make you to be a pillar in the sanctuary of my God, permanently secure. I will write on you the name of my God and the name of the city of my God—the New Jerusalem, descending from my God out of heaven. And I’ll write my own name on you. So the one whose heart is open let him listen carefully to what the Spirit is now saying to all the churches.
