Revelation 21 teaches us that God, through Christ, is making all things new - including a new heavens and a new earth. Those who trust in Christ and are adopted into the eternal, multi-ethnic (every tribe, tongue, and nation will be represented) family of God will spend eternity with Christ and with one another in this new creation. Today, whenever and wherever people participate in Kingdom life, it is an "appetizer" of the feast that will be served in eternity.
