The Seven Last Plagues
Could this be one of it?
Revelation 15:1
Then I saw another sign in heaven, great and marvelous: seven angels having the SEVEN LAST PLAGUES, FOR IN THEM THE WRATH OF GOD IS COMPLETE.
The last repentant sinner at this time has heard the call of mercy and turned to God. Then these just judgments of God will fall on the unrepentant in a shelterless world.
Daniel 12:1
At that time Michael shall stand up, the great prince who stands watch over the sons of your people; and THERE SHALL BE A TIME OF TROUBLE, such as never was since there was a nation, even to that time. And at THAT TIME YOUR PEOPLE SHALL BE DELIVERED, every one who is found written in the book.
