Armageddon precedes the Millennium (The sheep and the Goats) and the Great White Throne follows the Millennium.

A Day is like a thousand years……2Peter 3:8
It is now approximately 2000 years since the birth of Christ, 4000 years since Abraham and about 4500 years since the flood of Noah. The time of Adam is thought to be about 6000 years ago.
Peter says that a day is like a thousand years. We are about 6 millennia since Adam. If Christ were to come back now and begin his millennial reign, God will have completed his rescue plan in 6 days and rested on the seventh just as he did with Creation.
After the seventh millennium is over, God will make all things new and God will live with his people in a New Jerusalem.
When Christ returns, He will redeem His people from the Earth (the rapture) and raise the dead in Christ (the first resurrection). The Nations who rejected the Gospel will be left behind to suffer the Bowls of God’s Wrath. They will be separated into the Sheep and the Goats according to how they treated God’s People. There will also be 144000 Jews on the Earth who have been sealed and protected from God’s Wrath. The Nation of Israel will be restored for one Millennium to fulfill God’s promises to Israel. The Christians will be in Heaven with Christ in Heaven during the Millennium. When the Millennium is over, God will make all things New. The Church will descend from Heaven like a Bride for Christ and God will dwell with all His people on a New Earth in a New Jerusalem.
The Nations (Pagans / Gentiles) are to be gathered before Christ when he returns with His army of believers. The Nations who are gathered before Christ and His army (the believers) will be separated into the ‘Sheep’ and the ‘Goats’ according to the way that they treated God’s people. This will happen at the Battle of Armageddon which will be the final event before the Millennium starts.
At the end of the Millennium, the dead outside of Christ will be raised for Judgment at the Great White Throne.
If anybody’s name is not in the Book of life, they will be thrown into the Lake of Fire for Eternity.
In Eternity, God’s People will be with Him in the New Jerusalem. There is also another group called the New Nations which are not God’s people but, somehow, they escape the Lake of Fire.
The Sheep and The Goat Judgment is the Battle of Armageddon which is for pagans who are living at the time Christ returns. Zachariah Ch 14 tells us that some of the pagans who are living when Christ returns will survive Armageddon and become the Nations on Earth during the Millennium and perhaps in Eternity as well. It is likely that they are the Sheep who were kind to God’s people and this is their reward which was prepared for them before the begining of the world.
