Then I, John saw a new heaven and a new earth. The former heaven and the former earth had passed away, and the sea was no more. I also saw the holy city, a new Jerusalem, coming down out of heaven from God prepared as a bride adorned for her husband.
Revelation 21:1-2
John sees a new heaven and a new earth. The old pass away as a new heaven and a new earth emerge. In the end, we don’t go to heaven when we die. Heaven comes to us as heaven and earth unite like a bride and groom on their wedding day. The world ends with the marriage of heaven and earth.
This is what the New Testament is all about. Heaven comes to earth when Jesus the Son of God becomes a tiny baby. Heaven comes to earth when Jesus dies on the cross and the veil between heaven and earth is torn. Heaven comes to earth when the Holy Spirit descends upon the Church at Pentecost. Heaven comes to earth through all these ways that are amazing but also incomplete. At the end of time, heaven will come down to earth completely.
