The sixth seal, seventh trumpet, and seventh vial describe a series of events that occur during the period just prior to, and immediately following the second coming of Jesus Christ. While some of these events differ, all 3 passages are linked together by the mention of God’s wrath coming to the nations. This is most likely the Battle of Armageddon. All 3 passages also mention an earthquake. The 7th trumpet and vial both mention voices, thunderings, lightnings, and an earthquake.
And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood; And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind. And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places. And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains; And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb: For the great day of his wrath is come; and who shall be able to stand? (Revelation 6:12-17)
Enter into the rock, and hide thee in the dust, for fear of the LORD, and for the glory of his majesty. (Isaiah 2:10)
And they shall go into the holes of the rocks, and into the caves of the earth, for fear of the LORD, and for the glory of his majesty, when he ariseth to shake terribly the earth. In that day a man shall cast his idols of silver, and his idols of gold, which they made [each one] for himself to worship, to the moles and to the bats; To go into the clefts of the rocks, and into the tops of the ragged rocks, for fear of the LORD, and for the glory of his majesty, when he ariseth to shake terribly the earth. (Isaiah 2:19-21)
And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become [the kingdoms] of our Lord, and of his Christ; and he shall reign for ever and ever. And the four and twenty elders, which sat before God on their seats, fell upon their faces, and worshipped God, Saying, We give thee thanks, O Lord God Almighty, which art, and wast, and art to come; because thou hast taken to thee thy great power, and hast reigned. And the nations were angry, and thy wrath is come, and the time of the dead, that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth. And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail. (Revelation 11:15-19)
And the seventh angel poured out his vial into the air; and there came a great voice out of the temple of heaven, from the throne, saying, It is done. And there were voices, and thunders, and lightnings; and there was a great earthquake, such as was not since men were upon the earth, so mighty an earthquake, [and] so great. And the great city was divided into three parts, and the cities of the nations fell: and great Babylon came in remembrance before God, to give unto her the cup of the wine of the fierceness of his wrath. And every island fled away, and the mountains were not found. And there fell upon men a great hail out of heaven, [every stone] about the weight of a talent: and men blasphemed God because of the plague of the hail; for the plague thereof was exceeding great. (Revelation 16:17-21)
Response of the people
The tribes of the earth shall mourn and men’s hearts will melt.
And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory. (Matthew 24:30)
And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring; Men’s hearts failing them for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken. (Luke 21:25-26)
Howl ye; for the day of the LORD [is] at hand; it shall come as a destruction from the Almighty. Therefore shall all hands be faint, and every man’s heart shall melt: And they shall be afraid: pangs and sorrows shall take hold of them; they shall be in pain as a woman that travaileth: they shall be amazed one at another; their faces [shall be as] flames. (Isaiah 13:6-8)
