Wrong again.
Revelation 6:12-17 describes the 6th Seal with the sun, moon, and stars going dark. In Matthew 24:29 Jesus says the sun, moon, and stars go dark
after the tribulation of those days.
The Great Tribulation is not the wrath of God then. The wrath of God occurs after the Great Tribulation. I just proved it to you.
The Great Tribulation is the wrath of Satan.
Revelation 12:12
12Therefore rejoice,
ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea!
for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.
Now notice what happens next in this chapter and Revelation 13:
The Devil comes to Earth to persecute the woman and "her seed" and make war with the saints (saints are people like you and me - The Church or Body of Christ), to support the anti-Christ, Mark of the Beast, and the great tribulation. Why? Because he's angry and wants to cause a lot of pain for God's people before the end.
The Great Tribulation is conclusively the wrath of the devil and not God as you falsely claim.
