The 1000 years or the Millennium is described in Revelation chapter 20. “The rest of the dead lived not again until the thousand years were finished. “And when the thousand years are expired, Satan shall be loosed out of his prison, And shall go out to deceive the nations” (Revelation 20:5, 7, 8).
After the 1,000 Years
At the end of the millennium (when Jesus comes the third time) the wicked will be raised. Satan, will be loosed from his bonds and will then have an earth full of people (all the nations of the world) to control. “Satan shall … go out to deceive the nations … of the earth, … to gather them together to battle: the number of whom is as the sand of the sea. And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city” (Revelation 20:7-9).
The New Jerusalem
The New Jerusalem city would have descended down from Heaven with all the saints in it (Revelation 21:2,3). Satan will convince the wicked who are raised at the end of the millennium that if they unify, they can conquer the New Jerusalem. The nations will then unite and marshal their armies to surround the city.
But God’s fire will suddenly come down from heaven and all will be turned into ashes. “The wicked … shall be ashes under the soles of your feet in the day that I shall do this, saith the Lord of hosts” (Malachi 4:3).
This fire is originally intended for the devil and his angels (Matthew 25:41). But it will also destroy those who join the devil’s rebellion. “Fire came down from God out of heaven and devoured them. The devil, who deceived them, was cast into the lake of fire and brimstone” … “which is the second death” (Revelation 20:9, 10; 21:8). There is no resurrection from this death. That is what happens after the millennium.
