Revelation 22:3-5

Nothing that is under God's curse will be found in the city. The throne of God and of the Lamb will be in the city, and his servants will worship him. They will see his face, and his name will be written on their foreheads. There shall be no more night, and they will not need lamps or sunlight, because the Lord God will be their light, and they will rule as kings for ever and ever.
