A New Heaven And A New Earth - Isaiah 65:17-18

Isaiah 65:17-18 ESV 

“For behold, I create new heavens

and a new earth,

and the former things shall not be remembered

or come into mind.

But be glad and rejoice forever

in that which I create;

for behold, I create Jerusalem to be a joy,

and her people to be a gladness.

Revelation 21:1

Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and the sea was no more.

The new heaven and earth represent the creation of man into the image of Christ. 

Revelation 21:2-3

And I saw the holy city, new Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband. And I heard a loud voice from the throne saying, “Behold, the dwelling place of God is with man. He will dwell with them, and they will be his people, and God himself will be with them as their God.

The new Jerusalem coming down from heaven is the Bride of Christ. This is the dwelling place of God because He is with us.
