those who are standing before the Great White Throne Judgment were dead yet they stood before the Lord then sent to the place of eternal torment.
Rev 20:11-15
11 Then I saw a great white throne and him who was seated on it. From his presence, earth and sky fled away, and no place was found for them. 12 And I saw the dead, great and small, standing before the throne, and books were opened. Then another book was opened, which is the book of life. And the dead were judged by what was written in the books, according to what they had done. 13 And the sea gave up the dead who were in it, Death and Hades gave up the dead who were in them, and they were judged, each one of them, according to what they had done. 14 Then Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire. 15 And if anyone’s name was not found written in the book of life, he was thrown into the lake of fire.
Jesus is not wasting HIS time Judging the who are standing before HIM that came from the grave, the sea, and the earth both small and great. This is not figurative or descriptive it is normative of what Jesus said Eternal judgment would be.
I person who died before they were saved and this Appointed Judgment Day will stand before the Lord that was dead but now alive facing The Eternal God in and Eternal judgment.
Those who hold to annihilationism fail to see how the position does not address those who died unsaved that must stand at this Great White Throne. They would have you believe once you are dead that it.
