The Millennium

“The wolf will live with the lamb, the leopard will lie down with the goat, the calf and the lion and the yearling together, and a little child will lead them.” Isaiah 11:6
We read in Revelation 20:1-6 about the thousand year reign of Christ that follows the Great Tribulation. During this time Satan is bound, and from reading other parallel passages in Scripture, it would seem that God restores the earth to the state it was in before the Fall of man. Jesus will be reigning from Jerusalem as King over the whole earth, and we will reign with Him, enforcing His righteous standard on those people who are born during this time: the descendants of those believers who survive the Tribulation.
It will be a time when there is no more curse. Creation will once again live in harmony, “they will neither harm nor destroy on all My holy mountain, for the earth will be full of the knowledge of the Lord as the waters cover the sea” (Isa. 11:9). There will be perfect knowledge of God, everyone will know Him and worship Him.
This is not the eternal state that we will enter into. There is one final judgement, where Satan is released one last time. After this is the Great White Throne judgement, then we enter into glorious eternity.
