Seventh Seal (God's Wrath)
The Seventh Trumpet
Rev 11:15 Then the seventh angel sounded: And there were loud voices in heaven, saying, "The kingdoms of this world have become the kingdoms of our Lord and of His Christ, and He shall reign forever and ever!"
The 7th Trumpet heralds in the Millennium Rule of Jesus, when God has finished His work with men with all prophecies fulfilled and all mysteries revealed.
It is done! for God will complete His work with men on earth by the end of His Rule.
Rev 16:17 Then the seventh angel poured out his bowl into the air, and a loud voice came out of the temple of heaven, from the throne, saying, "It is done!"
Christ Millennium Rule
Rev 11:16-17 And the twenty-four elders who sat before God on their thrones fell on their faces and worshiped God, saying: "We give You thanks, O Lord God Almighty, The One who is and who was and who is to come, Because You have taken Your great power and reigned."
The whole heaven rejoices that our Lord Jesus will come again to earth for His Millennium Rule.
At the end of His rule, all men will appear before the great White Throne for judgment, and thereafter, the creation and New Heaven and New Earth.
Rev 11:18 The nations were angry, and Your wrath has come, and the time of the dead, that they should be judged, and that You should reward Your servants the prophets and the saints, and those who fear Your name, small and great, and should destroy those who destroy the earth."
The Seventh Trumpet/Bowl
Rev 16:18-20 And there were noises and thunderings and lightnings; and there was a great earthquake, such a mighty and great earthquake as had not occurred since men were on the earth. Now the great city was divided into three parts, and the cities of the nations fell. And great Babylon was remembered before God, to give her the cup of the wine of the fierceness of His wrath. Then every island fled away, and the mountains were not found.
For Jerusalem - Before Jesus comes for His Millennium Rule, the greatest earthquake ever will see Jesus dividing Mount Olives to saved the 144,000 Israelites from Jerusalem. More earthquakes will flattened the mountains around Jerusalem for Jesus to establish His kingdom.
Rest of the World - These great earthquakes will destroy all their cities, kill all islanders with huge tsunamis, and flatten all mountains, resulting to the killing of possibly 70-80% of the population.
Babylon - the high and mighty 'West', which was once the servant of God and champion for Christianity will be annihilated for destroying the faith of saints with the abominable UN Human Rights.
Rest of Mankind
Rev 16:21 And great hail from heaven fell upon men, each hailstone about the weight of a talent. Men blasphemed God because of the plague of the hail, since that plague was exceedingly great.
All those who escaped death from the great earthquakes, will face the great hail, which will kill many.
Men will blaspheme God for the plagues of His wrath are excruciating. By the end of the 7th trumpet, possibly 90% of mankind would have been killed before the Millennium Rule.
Ark Taken Up to Heaven
Rev 11:19 Then the temple of God was opened in heaven, and the ark of His covenant was seen in His temple. And there were lightnings, noises, thunderings, an earthquake, and great hail.
The Ark of the Covenant was taken up to heaven thereby ending Mosaic Old Covenant or Judaism at the death of Jesus, which at the same time established the New Covenant of His Blood.
