John 16:33

³³"I have told you these things, so that in me you may have peace. In this world you will have trouble. But take heart! I have overcome the world."

Revelation 3:12

¹²Him who overcomes I will make a pillar in the temple of my God. Never again will he leave it. I will write on him the name of my God and the name of the city of my God, the new Jerusalem, which is coming down out of heaven from my God; and I will also write on him my new name.
