The seventh bowl is significant for several reasons. It is the conclusion and final expression of God's wrath. Since the first
introduction of the seven angels with the seven plagues, the apostle John sees that they represent the last of God's wrath, and when
the last bowl is dispensed, someone very near God says, "it is done."
Then I saw another sign in heaven, great and marvelous, seven angels who had seven plagues, which are the
last, because in them the wrath of God is finished. (Rev 15:1)
Then the seventh angel poured out his bowl upon the air, and a loud voice came out of the temple from the
throne, saying, "It is done." (Rev 16:17)
The seventh bowl / plague (Rev 16:17-21):
1. Poured upon the air.
2. Amidst flashes of lightening and peals of thunder, the greatest earthquake ever experienced in human history
causes islands to significantly move from their location and mountains to fall. All of the cities of the world fall and are destroyed,
and a severe storm of huge hailstones, weighing close to 100 pounds, fall around the world
3. The great earthquake appears to be the same earthquake associated with the sixth seal:
I looked when He broke the sixth seal, and there was a great earthquake; and the sun became black as
sackcloth made of hair, and the whole moon became like blood; and the stars of the sky fell to the earth, as a fig tree casts its
unripe figs when shaken by a great wind. The sky was split apart like a scroll when it is rolled up, and every mountain and island
were moved out of their places. (Rev 6:12-14)
The seventh bowl is significant for being the last of God's wrath. From this moment on, God will no longer have a reason for anger,
because He has pronounced judgment on the last of sin. This final judgment is celebrated in heaven.
After these things I heard something like a loud voice of a great multitude in heaven, saying, "Hallelujah!
Salvation and glory and power belong to our God; because His judgments are true and righteous; for He has judged the great harlot who
was corrupting the earth with her immorality, and He has avenged the blood of His bond-servants on her." And a second time they said,
"Hallelujah! Her smoke rises up forever and ever." (Rev 19:1-3)
And the twenty-four elders and the four living creatures fell down and worshiped God who sits on the throne
saying, "Amen. Hallelujah!" (Rev 19:4)
And a voice came from the throne, saying, "Give praise to our God, all you His bond-servants, you who fear
Him, the small and the great." (Rev 19:5)
Then I heard something like the voice of a great multitude and like the sound of many waters and like the
sound of mighty peals of thunder, saying, "Hallelujah! For the Lord our God, the Almighty, reigns."
With judgment passed, all that remains is Jesus Christ executing that sentence upon all those human beings who are left.
