Brief Overview: The millennium is the thousand-year reign of Christ with His saints in heaven between the first and second resurrections. During this time the wicked dead will be judged; the earth will be utterly desolate, without living human inhabitants, but occupied by Satan and his angels. At its close Christ with His saints and the Holy City will descend from heaven to earth. The unrighteous dead will then be resurrected, and with Satan and his angels will surround the city; but fire from God will consume them and cleanse the earth. The universe will thus be freed of sin and sinners forever. (Rev. 20; 1 Cor. 6:2,3; Jer. 4:23-26; Rev. 21:1-5; Mal. 4:1; Eze. 28:18, 19.)

Why it is important to know the truth about the millennium: There are many erroneous teachings about the millennium, including the idea some will be given a second chance after the second coming. This is a false security leading many to disregard the exhortation of Paul, “For God says, “At just the right time, I heard you. On the day of salvation, I helped you.”Indeed, the “right time” is now. Today is the day of salvation.” 2 Corinthians 6:2 NLT

Why it is important to understand the millennium in light of the cross: Only when we get to heaven will we see and realize what Jesus left to come and die for us.

Further Study on the Millennium

What happens to the earth when Jesus comes?

Look! The Lord is about to destroy the earth and make it a vast wasteland. He devastates the surface of the earth and scatters the people. Isaiah 24:1 NLT

What happens to all of the wicked?

In that day those the Lord has slaughtered will fill the earth from one end to the other. No one will mourn for them or gather up their bodies to bury them. They will be scattered on the ground like manure. Jeremiah 25:33 NLT

What happens to the righteousness?

We tell you this directly from the Lord: We who are still living when the Lord returns will not meet him ahead of those who have died. For the Lord himself will come down from heaven with a commanding shout, with the voice of the archangel, and with the trumpet call of God. First, the Christians who have died will rise from their graves. Then, together with them, we who are still alive and remain on the earth will be caught up in the clouds to meet the Lord in the air. Then we will be with the Lord forever. 1 Thessalonians 4:15-17 NLT

Note: When Jesus comes the wicked are all slain, the righteous are all taken to heaven, and the earth is left in a desolate state (“without form and void” Jer. 4:23; as a “bottomless pit” Rev. 20:1).

How long is Satan bound to the earth?

Then I saw an angel coming down from heaven with the key to the bottomless pit and a heavy chain in his hand. He seized the dragon—that old serpent, who is the devil, Satan—and bound him in chains for a thousand years. The angel threw him into the bottomless pit, which he then shut and locked so Satan could not deceive the nations anymore until the thousand years were finished. Afterward he must be released for a little while. Revelation 20:1-3 NLT

Note: Satan is chained up by circumstances. All the wicked are dead. The righteous are in heaven, and he has no one to tempt or torment. Before his expulsion from heaven he thought he would make a better ruler than God. See Isaiah 14:14. Satan now gets to roam the world for a thousand years and consider the fruits of his empire.

What will the righteous be doing during the thousand years?

Then I saw thrones, and the people sitting on them had been given the authority to judge. And I saw the souls of those who had been beheaded for their testimony about Jesus and for proclaiming the word of God. They had not worshiped the beast or his statue, nor accepted his mark on their foreheads or their hands. They all came to life again, and they reigned with Christ for a thousand years. Revelation 20:4 NLT

Whom shall they be judging?

Don’t you realize that someday we believers will judge the world? And since you are going to judge the world, can’t you decide even these little things among yourselves? Don’t you realize that we will judge angels? So you should surely be able to resolve ordinary disputes in this life. 1 Corinthians 6:2-3 NLT

Jesus spoke of two resurrections.

Don’t be so surprised! Indeed, the time is coming when all the dead in their graves will hear the voice of God’s Son, and they will rise again. Those who have done good will rise to experience eternal life, and those who have continued in evil will rise to experience judgment. John 5:28-29 NLT

Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice, And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation. John 5:28-29 KJV

When are the wicked dead raised?

This is the first resurrection. (The rest of the dead did not come back to life until the thousand years had ended.) Blessed and holy are those who share in the first resurrection. For them the second death holds no power, but they will be priests of God and of Christ and will reign with him a thousand years.Revelation 20:5-6 NLT

What does Satan do when they are raised?

When the thousand years come to an end, Satan will be let out of his prison. He will go out to deceive the nations—called Gog and Magog—in every corner of the earth. He will gather them together for battle—a mighty army, as numberless as sand along the seashore. Revelation 20:7-8 NLT

What descends down from God?

And I saw the holy city, the new Jerusalem, coming down from God out of heaven like a bride beautifully dressed for her husband. Revelation 21:2 NLT

What does Satan attempt and what happens?

And I saw them as they went up on the broad plain of the earth and surrounded God’s people and the beloved city. But fire from heaven came down on the attacking armies and consumed them. Revelation 20:9 NLT

What is this fire called?

Then death and the grave were thrown into the lake of fire. This lake of fire is the second death. Revelation 20:14 NLT

What will God create from the ashes?

But the day of the Lord will come as unexpectedly as a thief. Then the heavens will pass away with a terrible noise, and the very elements themselves will disappear in fire, and the earth and everything on it will be found to deserve judgment. Since everything around us is going to be destroyed like this, what holy and godly lives you should live, looking forward to the day of God and hurrying it along. On that day, he will set the heavens on fire, and the elements will melt away in the flames. But we are looking forward to the new heavens and new earth he has promised, a world filled with God’s righteousness. 2 Peter 3:10-13 NLT

What will the new earth be like?

In those days people will live in the houses they build and eat the fruit of their own vineyards. Unlike the past, invaders will not take their houses and confiscate their vineyards. For my people will live as long as trees, and my chosen ones will have time to enjoy their hard-won gains. They will not work in vain, and their children will not be doomed to misfortune. For they are people blessed by the Lord, and their children, too, will be blessed. I will answer them before they even call to me. While they are still talking about their needs, I will go ahead and answer their prayers! The wolf and the lamb will feed together. The lion will eat hay like a cow. But the snakes will eat dust. In those days no one will be hurt or destroyed on my holy mountain. I, the Lord, have spoken!” Isaiah 65:21-25 NLT

What promise of God does John receive in vision?

Then I saw a new heaven and a new earth, for the old heaven and the old earth had disappeared. And the sea was also gone. And I saw the holy city, the new Jerusalem, coming down from God out of heaven like a bride beautifully dressed for her husband. I heard a loud shout from the throne, saying, “Look, God’s home is now among his people! He will live with them, and they will be his people. God himself will be with them. He will wipe every tear from their eyes, and there will be no more death or sorrow or crying or pain. All these things are gone forever.” And the one sitting on the throne said, “Look, I am making everything new!” And then he said to me, “Write this down, for what I tell you is trustworthy and true.” Revelation 21:1-5 NLT
