Amillennialists, Postmillennialists, and even some Premillennialists view the Sheep/Goat judgment of Matthew 25:31-46 and the Great White Throne judgment of Revelation 20:11-15 as being the same event. But a close examination reveals that these two judgments are not the same judgment.
1. The timing of the Sheep/Goat judgment happens in connection with the second coming of Christ (see Matt 25:31-32). Jesus comes in glory with His angels, sits on His glorious throne and all the nations are gathered before Him. The Great White Throne judgment takes place after the return of Christ (Rev 19) and the thousand year reign of Christ with the saints (Rev 20:4-7). After the thousand years are completed (20:7) the Great White Throne judgment takes place (20:11-15).
It may surprise some to know that God’s kingdom program for this earth goes back to the first chapter of the Bible—Genesis 1. God created man to represent God on Earth and rule over His wonderful creation. Genesis 1:26-28 states:
Any discussion of God's kingdom and kingdom purposes must take into account what can be called God's universal kingdom. On several occasions the Old Testament affirms God's eternal sovereign rule over all things. For example, Psalm 145:13 states:
Your kingdom is an everlasting kingdom, And Your dominion endures throughout all generations.
Psalm 103:19 also declares:
The LORD has established His throne in the heavens, And His sovereignty rules over all.
Sometimes I get complaints for claiming that non-dispensationalists believe that the NT “reinterprets” the OT. While I certainly acknowledge that some do not use that specific term, we must be honest and acknowledge that some have. Here is a sample of those who explicitly use “reinterpret” language (note that the emphases below are mine):
A New Creation Model affirms the presence of nations not only in the Millennium, but also in the Eternal State. Three references indicate this:
Rev 21:24-26: The nations will walk by its light, and the kings of the earth will bring their glory into it. In the daytime (for there will be no night there) its gates will never be closed; and they will bring the glory and honor of the nations into it.
Rev 22:3: in the middle of its street On either side of the river was the tree of life, bearing twelve kinds of fruit, yielding its fruit every month; and the leaves of the tree were for the healing of the nations.
