Revelation 21:21-25

21 The twelve gates were twelve pearls, each gate made of a single pearl. The great street of the city was of pure gold, like transparent glass.

22 I did not see a temple in the city, because the Lord God Almighty and the Lamb are its temple.

23 The city does not need the sun or the moon to shine on it, for the glory of God gives it light, and the Lamb is its lamp.

24 The nations will walk by its light, and the kings of the earth will bring their splendor into it.

25 On no day will its gates ever be shut, for there will be no night there.

Revelation 21:1-5 

1 Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and there was no longer any sea.

2 I saw the Holy City, the new Jerusalem, coming down out of heaven from God, prepared as a bride beautifully dressed for her husband.

3 And I heard a loud voice from the throne saying, “Now the dwelling of God is with men, and he will live with them. They will be his people, and God himself will be with them and be their God.

4 He will wipe every tear from their eyes. There will be no more death or mourning or crying or pain, for the old order of things has passed away.”

5 He who was seated on the throne said, “I am making everything new!” Then he said, “Write this down, for these words are trustworthy and true.”
