Revelation 22:3-5

3No longer will there be any curse. The throne of God and of the Lamb will be in the city, and his servants will serve him. 4They will see his face, and his name will be on their foreheads.

5There will be no more night. They will not need the light of a lamp or the light of the sun, for the Lord God will give them light. And they will reign for ever and ever.
