Jesus brought heaven to earth in the incarnation. Jesus took earth to the right hand of the Father with His ascended resurrected body; He ascended back to heaven with the same body that came out of the grave. He is seated on the throne of Heaven as a sacrificial lamb, having been slain on earth by sinful men; He bears in Heaven the scars earth inflicted on Him. He is now the exalted human at the right hand of God; He is also God who became human. He who took earth to heaven will once again bring heaven back down to earth and both will become one.
“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.And I saw the holy city, the 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, “See, the home of God is among mortals. He will dwell with them; they will be his peoples, and God himself will be with them; he will wipe every tear from their eyes. Death will be no more; mourning and crying and pain will be no more, for the first things have passed away.”Revelation 21:1-4 (NRSV)
