The rapture and the Great White Throne Judgment are two very different events happening at different times.
I’ve looked into the question of when the Rapture happens and it’s pretty clear it comes before the Great Tribulation.
Meeting the Lord in the air to go to the banquet feast is a completely different situation than coming straight from Heaven at the battle Armageddon.
And the rapture can happen any moment. Whereas what’s described in the book of Revelation, multiple things must happen first before Christ comes back.
