If the Renewed Earth comes at the beginning of the millennium wouldn’t it be ruined by the unbelievers who die in it?
and wouldn’t Satan’s rebellion of Rev 20 and the fire from heaven have drastic consequences?
Rev. 20:7-9 says, “When the thousand years are over Satan will be released from his prison and will go out to deceive the nations in the four corners of the earth–Gog and Magog–to gather them for battle. In number they are like the sand on the seashore. They marched across the breadth of the earth and surrounded the camp of God’s people, the city he loves. But fire came down from heaven and devoured them.”
We don’t know anything about Eternity, so we don’t know what exactly will happen to Earth at the end of the Millennium. Rev. 20:9 says the fire from Heaven will devour the people who rebel at the end of the Millennium and surround the Holy City, but doesn’t say how that will impact the Earth itself. In any case, the Church will be in the New Jerusalem and will not participate in this final rebellion of mankind.
