Christ's Millennial Reign is the literal 1000 years of peaceful reign by Jesus on earth. (Isaiah 11 and 35)
The thousand-year literal reign of Jesus on earth will be ushered in by the Revelation of Christ—the coming of Jesus back to earth with ten thousands of His saints at the close of the Great Tribulation. At this time, He will judge the nations that dwell upon the face of the earth and Satan will be bound. It will be a reign of peace and blessing. The curse, which fell when Adam and Eve transgressed the command of God, will be lifted from all creation and the world will enjoy Christ's righteous government. The saints of God who will return with Jesus from Heaven after the Marriage Supper of the Lamb will rule and reign with Him on earth.
The Millennial Reign will close with the final Judgment from the Great White Throne.
