When Christ comes, the Church goes up and those who are left behind are separated into the Sheep and the Goats. This occurs after 1260 days of the Great Tribulation and corresponds to the Last Trumpet.
God pours out his Wrath upon the Nations of the Earth for up to 75 days after rapturing the Church. The Battle of Armageddon may only last 45 days. After the 1335 days, the Seventh Trumpet is over and the Millennium starts. The contents of the Scroll, the Book of Life, will be known. “The kingdom of the world has become the kingdom of our Lord and of his Christ, and he will reign for ever and ever.”
15The seventh angel sounded his trumpet, and there were loud voices in heaven, which said:
“The kingdom of the world has become the kingdom of our Lord and of his Christ,
and he will reign for ever and ever.”
16And the twenty-four elders, who were seated on their thrones before God, fell on their faces and worshiped God, 17saying:
“We give thanks to you, Lord God Almighty,
the One who is and who was,
because you have taken your great power
and have begun to reign.
18The nations were angry;
and your wrath has come.
The time has come for judging the dead,
and for rewarding your servants the prophets
and your saints and those who reverence your name,
both small and great—
and for destroying those who destroy the earth.”
19Then God’s temple in heaven was opened, and within his temple was seen the ark of his covenant. And there came flashes of lightning, rumblings, peals of thunder, an earthquake and a great hailstorm.
