Have you checked out my website http://www.millennialkingdom.net as yet? It is where you will find resources to prepare you for the soon-coming Millennial Kingdom where Jesus reigns with the glorified Saints on this earth.
One purpose of the thousand-year reign is to allow for the fulfillment of the promises God made with Jesus, Israel, the Saints, and the Creation, to vindicate His Holy name. The Messiah must reign over His kingdom until He has defeated all His enemies.
“Thus says the Lord God: It is not for your sake, O house of Israel, that I am about to act, but for the sake of my holy name, which you have profaned among the nations to which you came. And I will vindicate the holiness of my great name, which has been profaned among the nations, and which you have profaned among them. And the nations will know that I am the Lord, declares the Lord God, when through you I vindicate my holiness before their eyes.“ Ezekiel 36:22-24
“But each in his own order: Christ the first fruits, then at His coming those who belong to Christ. Then comes the end, when He delivers the kingdom to God the Father after destroying every rule and every authority and power. For He must reign until He has put all His enemies under His feet.” 1 Corinthians 15:23-25
The main purpose of the Millennium is to prepare the Nations and Saints for the Father coming in the fullness of His glory. Then, there will be a new heaven and new earth free of sin and death, identifying it as the Eternal State.
Revelation 21:1-4 “Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and the sea was no more. And I saw the holy city, new Jerusalem, coming down out of the heaven from God, prepared as a bride adorned for her husband. And I heard a loud voice from the throne saying, “Behold, the dwelling place of God is with man. He will dwell with them, and they will be his people, and God himself will be with them as their God.”
Revelation 22:3-5 “No longer will there be anything accursed, but the throne of God and of the Lamb will be in it, and his servants will worship him. They will see his face and his name will be on their foreheads. And night will be no more. They will need no light of lamp or sun, for the Lord God will be their light, and they will reign forever and ever.”
