What will be the setup of nations in the eternal state?
The eternal state will retain the millennial setup: the nations will continue, Israel will be head of the nations, and Christ will reign as King of kings and Lord of lords. God and the Lamb will be at the center, with no more curse, and His servants serving and seeing His face.
Les explains that because the Davidic house and kingdom are established forever, not merely for a thousand years, the millennial economy carries over into the eternal state. Revelation 22 shows the nations present with the same setup as the millennium: Israel as the head of the nations and Christ as King of kings and Lord of lords. There will be no more curse; the throne of God and of the Lamb will be in it, God will be in the very center, and His servants—believers from the ages—will serve Him and see His face. Les notes we should not try to put a face on God, for God is eternal and Spirit.
