The biblical vision of eternity is not an escape from the material world but its restoration. Isaiah first prophesied a new heaven and new earth where the former things would not be remembered (Isaiah 65:17). Peter described the present heavens and earth being dissolved by fire, with believers looking forward to 'new heavens and a new earth in which righteousness dwells' (2 Peter 3:13). Paul taught that creation itself groans in anticipation of liberation from bondage to decay (Romans 8:19-21). Revelation 21-22 provides the fullest picture: God descending to dwell among His people, wiping every tear, abolishing death, pain, and sorrow. The new Jerusalem — described in staggering dimensions of gold, jewels, and crystal — comes down from heaven to earth, not the other way around. Theologians debate whether God will annihilate the current cosmos and create from nothing, or purify and transform the existing creation. Either way, the promise is concrete and physical: resurrected bodies in a renewed world, with the tree of life bearing fruit and the river of life flowing from God's throne.
