The Thousand Year Reign:
(Read Revelation 20: 1-6). 
John saw an angel coming down from heaven with the key of the bottomless pit and a great chain (20:1). The angel seized the Antichrist and the false prophet were bound in chains and cast them alive into a bottomless pit for a thousand years.  This binding is different from the binding mentioned in the gospel account (Mark 3:27). The angel threw them in the bottomless pit so that Satan could not deceive the nations.  This period is known as the Millennium in which Christ will reign on earth with His saints. This is the only chapter that mentions the word "millennium" but it is repeated six times in the same chapter (Revelation 20: 2, 3, 4, 5, 6).  There are mainly three views about the millennium.  One theory says that the world is getting better through the gospel preaching and the church will emerge as a society of saints. Then Christ will return and reign for a thousand years.  But the Bible clearly teaches that this world is getting worse as the return of Christ draws near (1 Timothy 4:1; 2 Timothy 3:1-5).  Amillennialism teaches that there will be no thousand year reign. They say that Isaiah chapter 11 should not be taken literally, it is only allegorical.  If so, how can we take Isaiah 53 literally?   The premillennialism teaches that Christ will return prior to the Millennium and reign in righteousness for a thousand years.  This view is scriptural and held by the early church fathers. This is a literal, thousand year reign (Revelation 20: 3, 7). This happens between the two resurrections. The first resurrection includes the resurrection of Christ and all true believers (1 Corinthians 15: 23).  Blessed are those who are included in the first resurrection. Unbelievers will be raised at the end of millennium.  All those who are saved from Israel and gentile nations will enter the kingdom of Christ (Matthew 13:41-43). John saw the souls of martyrs there. They died for the testimony of Jesus and did not worship the beast.  During the millennium, this planet would return to its full blessing for a period of a thousand years.  Many Old Testament passages describe the blessings of millennium (Isaiah 2:2-4; 11:6, 8; Psalms 2:6-9). Christ first came to save the world from sin. Now He returns to reclaim the inheritance Adam lost due to sin. Believers will rule and reign with Christ during this golden age of peace and prosperity (Revelation 3:21; Luke 22:29, 30).  The earth will be a blissful place physically and spiritually.  Satan is bound and he cannot deceive the inhabitants of earth during this period.  John encourages believers to endure in the faith regardless of the suffering.
 
Satan’s Final Defeat:
(Read Revelation 20:7-10) 
When the thousand years end, Satan will be released for his final act of deception and rebellion (20:9).  He will go out to deceive the nations. This will result in a global rebellion against God. Gog and Magog, must not be confused with the nations mentioned in Ezekiel 38 and 39. Satan will gather the nations which will result in a global rebellion against Christ. How can there be anyone to follow Satan in this perfect era? Because the children born to believers during this period are born with the same sinful nature.  Perfect environment does not change sinners into saints.  Having a godly heritage does not make a sinner a saint either. Children born in the millennium are sinners and they must trust Christ to be born again.  The Devil who deceives nations and gathers them together for Gog and Magog battle.  This will be a global rebellion against God (20:9). As they surround God's people and the beloved city, fire from heaven will come down on the enemies and consume them.  Then the Devil will be thrown into the lake of fire where the beast and false prophet were.  This is a place of unending torment. Death is not an annihilation of life.  Nobody will enjoy hell with their friends.  John encourages us to remain faithful to Christ regardless of the suffering that may come. 
 
The Great White Throne Judgment:
(Read Revelation 20:11-15)
With Satan's final defeat, he is cast into the lake of fire. Hell is a place of torment.  John saw a great white throne and the one sitting on it. The earth and sky fled away from his presence. This is the final judgment. The one sitting on the throne is Jesus Christ (John 5:22, 27). White is symbolic of purity and perfect judgment (Isaiah 1:18). John saw the dead, great and small of all ages standing before the white throne judgment seat. As they appear, books were opened, including the book of life. In the book of life the names of God’s people are recorded. What is this book of life?  The book of life contains the names of every person born in this world.  Christ’s death is sufficient to save the entire world (1 John 2:2). There is no such thing as limited atonement. Christ died for the whole world (John 3:16).  Christ’s death is sufficient to save the whole world but efficient to save all those who believe in Christ.  Whoever calls upon the name of the Lord shall be saved (Romans 10:13). When a person chooses to reject Christ, his name will be removed from the book of life. Salvation is a gift from God. A gift is not a gift unless it is received (John 1:12). Those who reject this gift will be thrown into the lake of fire. Sinners will be judged according to their works recorded in the books (Romans 2:16).  The degree of their punishment is decided by their deeds (Luke 23:41). Our good deeds will not earn favor with God at the judgment seat. We are saved by grace through faith in Christ. This grace changes the way we live. Then death and grave will be thrown into the lake of fire. All unsaved will be raised from dead on that day and they will face judgment at the white throne. Their whole persons; spirit soul and body will be cast into the lake of fire. This is the second death. Death is the last enemy.  The last enemy that will be destroyed is death (1 Corinthians 15:26). There is no second chance to get saved.  Why should anyone in their right mind reject Christ? The wages of sin is death which is eternal separation from God.  But the gift of God is eternal life through Jesus Christ our Lord (Romans 6:23). Those who embrace Christ will be part of the first resurrection.  Those who are saved overcome sin by faith in Christ (1 John 5:4-5). They are saved by grace through faith in Christ.  Have you received Jesus Christ as your Lord and savior?
