And the seventh one poured out his bowl into the air, and a loud voice came out of the temple from the throne, saying; “It is done.” And there were flashes of lightning and voices and peals of of thunder, and a great earthquake occurred, such as has not been ever since human beings came upon the earth, so powerful was the great earthquake. And the great city was split into three parts, and the cities of the nations fell. And Babylon the great was remembered before God to give her the cup of the wine of the fury of His wrath. And every island fled away, and the mountains were not found. And great hailstones about a talent in weight came down from heaven upon the people, and the people blasphemed God for the plague of the hail, because its plague was extremely great. Revelation 16: 17-21
From the midst of lightning flashes, voices, and thunder – a phenomenon always associated with the throne of God – and at the pouring out of the bowl, God announces the completion of His wrath with “It is done.”
As such, a great earthquake occurs that shatters the great mystical city: end-time Babylon. It is a literal earthquake, as the dispersal of the mountains and islands indicate. But at the same time, it is a figurative earthquake that splits apart the three unified components that make up Satan’s kingdom; that being the papacy, apostate Protestantism, and modern spiritism (see Rev. 16: 13, 14).
When that split occurs, the figurative earthquake also shakes apart the unity of the political, secular, and religious powers of the world that supported the unholy trinity (the dragon, sea beast, and and false prophet). Those cities fall too from the literal earthquake. Having been deceived by promises of peace and safety, those aligned with the beast furiously turn weapons, meant to be used against God’s people, upon themselves and their leaders.
On top of that, God’s wrath includes the manifestation of great hailstones. The measurement of a talent varies in history among different people at different times. So its weight is uncertain, being anywhere from fifty to over one hundred pounds.
Even so, instead of acknowledging that this and the other plagues are consequences brought on by their own hatred and oppression of God’s people, the wicked still blaspheme God.
