John saw a new heaven, a new earth, and a New Jerusalem, the city where God will dwell permanently with his people.

Revelation 21:1-4

21 Then in the vision I saw a new heaven and a new earth. The first heaven and the first earth had disappeared, and the oceans no longer existed. 2 I saw God’s holy city, which is the new city of Jerusalem. It was coming down out of heaven from God. The city had been prepared and decorated {God had prepared and decorated the city} as [SIM] a bride is decorated {decorates herself} beautifully in order to marry her husband. 3 I heard a loud voice that spoke from the throne of God. It said, “Listen to this! Now God will live with people. He will live right in the midst of them [DOU]! They will be his people. God himself will be with them, and he will be their God. 4 As a result, he will cause them to no longer be sad. It will be as though he will [MTY] wipe every tear from their eyes. None of them will ever again die or mourn or cry [DOU] or suffer pain, because the former things that make us sad will have disappeared.”
