Let’s note first that Peter describes the antediluvian or first world as “the world that then existed” and was destroyed by water. The second world is “the world which now exists” —a world that will be cleansed by fire to make way for the third world, “a new earth in which righteousness dwells” (2 Peter 3:6, 7, 13). The “third world” will be as real as the first two. JTL28 9.1
In Revelation, John describes the New Jerusalem, as the capital of the new earth with words that convey beauty, glory, and splendor. From the throne of God in the center of the city flows the “river of water of life” (Revelation 22:1). There will be dwelling places—real homes—for the ransomed, as well as unlimited opportunities to practice creative horticulture (without weeds or drought!), architecture, and physical and intellectual activities. We will not be angels in heaven; we will be ourselves—glorified and immortal. Jesus will both eat and drink with us there (Mark 14:25). JTL28 9.2
The New Jerusalem will be the religious center of the kingdom, to which the redeemed come both regularly and unceasingly, to worship and learn of God’s ways. Singing and fellowship will be an important and joyful part of worship in the new earth. The new earth will be a kingdom governed by righteousness, faithfulness, and peace; a full restoration of what God had planned for His original creation in Eden. Best of all, God will dwell among His people: “They shall see his face, and his name shall be on their foreheads” (Revelation 22:3, 4). JTL28 9.3
