When will Jesus sit on His crown with all glory having put down all rule and authority? Mat 25:31
Who are the angels with Him? What is an angel for that matter?
Jesus deals with nations here; not individuals.
Are the nations saved, or are they righteous in their actions? Mat 25:35-40.
Who are His brethren of Mat 25:40?
Where will those goat nations be sent? Mat 25:41. At this point the lake of fire isn’t a part of the equation because the great white throne judgment has not occurred.
Just prior to the great white throne judgment of Rev 20:11 the following events happen. Just because some are saved in the millennium does not ensure that all are.
Rev 20:7 And when the thousand years are expired, Satan shall be loosed out of his prison,
Rev 20:8 And shall go out to deceive the nations which are in the four quarters of the earth, Gog and Magog, to gather them together to battle: the number of whom is as the sand of the sea.
Rev 20:9 And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them.
