Revelation 21:23-27

And the city hath no need of the sun, neither of the moon, to shine upon it: for the glory of God did lighten it, and the lamp thereof is the Lamb. And the nations shall walk amidst the light thereof: and the kings of the earth bring their glory into it. And the gates thereof shall in no wise be shut by day (for there shall be no night there): and they shall bring the glory and the honor of the nations into it: and there shall in no wise enter into it anything unclean, or he that maketh an abomination and a lie: but only they that are written in the Lamb’s book of life.
