One day in the future God will usher in the new heaven and new earth.
And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband. And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God. And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away. (Revelation 21:2-4 KJV)
The Apostle John records in scripture about the new heaven and earth. He was the last of the Apostles to be alive on this earth chosen by God to have a glimpse into the future as this new Jerusalem descends down from the heavenly realm to rest upon the earth.
This future magnificent spiritual event, which is beyond recounting in terms man could understand from his finite viewpoint upon this earth, John is inspired to describe as holy and pure, like a bride when presented to her husband. A wedding ceremony is a biblical picture of God and his church. Most wedding ceremonies today are far removed from this sacred analogy or holy pattern given from God over two thousand years ago. God’s Word never changes and the pureness and holiness of the bride of Christ is a relevant precept for God’s people to contemplate upon today.
This glorious new heavenly city will be a place of joy and eternal spiritual rest for man as he is now existing in perfect fellowship with God in the eternal realm having no more sadness, tears, darkness or death to contend with. All things will be new as the old earth and everything in it burns and melts away.
We cannot even begin to imagine how magnificent the new heaven and earth will be. We can draw upon and hide inside our hearts the biblical metaphors given throughout the cannon of scripture which depict the new heaven and new earth as perfect, holy and glorious.
