21st Century Revelation's premise is that we are living in the End Times right before the Rapture. Four seals and five trumpets occur before the Tribulation. World War III (China, United States, India) occurs during the first half of the Tribulation. World War IV (Russia-Islamic War, Gog/Magog), seven bowls and World War V (Armageddon) occur during the second half.

I saw another sign in heaven, great and marvelous, seven angels having the seven last plagues; for in them is filled up the wrath of God (Revelation 15:1).

Revelation 15 describes seven angels with pure white robes and gold sashes. They were given harps and bowls of the wrath of God that describe seven future plagues. They sang the song of Moses and the Lamb. The temple was filled with the glory of God and no one can enter the throne until the bowls were completed (Revelation 15:8).

They sing the song of Moses the servant of God, and the song of the Lamb, saying, Great and marvelous are thy works, Lord God Almighty; just and true are thy ways, thou King of saints. Who shall not fear thee, O Lord, and glorify thy name? for thou only are holy: for all nations shall come and worship before thee; for thy judgments are made manifest (Revelation 15:3-4).

The unholy trinity of Satan, Antichrist and False Prophet rule during the second half of the Tribulation. During that time, the seven angels pour out seven bowl of the wrath of God. Salvation in Jesus Christ is still available and the Tribulation Saints are saved but time runs out quickly. Everyone must make an individual choice to follow God or follow Antichrist. The choice determines a person's eternal destiny.

< Antichrist rules the Beast: World Government Revelation 13:4, 7
< False Prophet rules the 2nd Beast: World Religion Revelation 13:12-13
< Mark controls the World: World Economy Revelation 13:16-17

The Bible is not clear when the bowl judgments begins. The bowls start after Antichrist's coronation and World War IV (Russian-Islamic War, Gog/Magog) and before armies gather at the valley of Megeddo for World War V. The 7th seal, bowl, trumpet occur at the Second Coming.

Bowl 1 - Earth - Sores on People (Revelation 16:2)

The first angel pours the bowl on the earth. The plague is sores on the people with the mark of the Beast and those who worship the image.

Bowl 2 - Sea to Blood (Revelation 16:3)

The second angel pours the bowl on the sea. The plague is the sea to blood. Every person in the sea dies.

Bowl 3 - Fresh Water to Blood (Revelation 16:4, 5-6, 7)

The third angel pours the bowl on fresh water. The plague is the rivers and springs turn to blood. God is just in His judgments because these people shed the blood of the saints and prophets.

Bowl 4 - Sun Scorched People (Revelation 16:8-9)

The fourth angel pours the bowl on the sun. The plague is the sun scorches people. They know God is bringing the plagues, curse God but refuse to repent.

Bowl 5 - Kingdom of the Beast in Darkness (Revelation 16:10-11)

The fifth angel pours the bowl on the throne of the beast. The plague is darkness on the kingdom of the Beast. People were in agony because of the pain from the sores and the darkness.
.

Bowl 6 - Euphrates River Dried Up for Armageddon (Revelation 16:12, 13-14, 15, 16)

The sixth angel pours the bowl on the Euphrates River that flows through Turkey, Syria, Iraq and Iran. The river dries up for the the kings of East (Asia). Three demonic spirits that look like frogs come out of the dragon, Beast (Antichrist) and False Prophet. They gather the armies of the world at the valley of Megiddo in northern Israel for Armageddon.

Bowl 7 - Storms at the End of Armageddon (Revelation 15:17-18, 19-21)

The seventh angel pours the bowl in the air. It is done. The Tribulation ends with the 7th seal, 7th trumpet, 7th bowl. Judgments describe lightning, thunder, voices, great hail, earthquakes, mountains fall and islands flee as part of the Second Coming. Mystery Babylon, Antichrist and False Prophet are are targets of God's wrath.

• 7th Seal - Revelation 8:1, 5
• 7th Trumpet - Revelation 10:7, 11:15, 19
• 7th Bowl - Revelation 16:17-18, 20-21
• Gog & Magog Ezekiel 38:20, 21-22
• Day of the Lord Zechariah 14:1-2, 3, 12, 15

Trumpet 6    World War III    200 Million Army    Revelation 9:14-16
Bowl 6         World War V     Kings of the East      Revelation 16:12

Bowls repeat from other judgments from God. During the time of Moses, there were ten plagues on Egypt (Exodus 7-12). Elements of four trumpet wars against a third of the earth, sea, fresh water and sun are found in five bowls (Revelation 8, 16). These repetitive topics follows the chiastic (ABCCBA) structure with the main theme in the middle of the book. See Revelation Outline, Revelation Views. The 6th trumpet (World War III) and the 6th bowl (World War V) refer to the Euphrates River and involve the kings of the east. These bowls occur during the last half of the Tribulation. God can use the natural supernaturally or performs supernatural miracles. God's purpose is redemption. He gives mercy and grace to the humble and justice and judgment to the rebellious. In everything, God is glorified.

7th Trumpet: In the days of the voice of the seventh angel, when he shall begin to sound, the mystery of God should be finished, as he has declared to his servants the prophets (Revelation 10:7).
7th Bowls: The seventh angel poured out his bowl into the air; and there came a great voice out of the temple of heaven, from the throne, saying, It is done (Revelation 16:17).

The book of Revelation is not sequential but a spiral of parallel events that have shorter and shorter time spans until the return of Jesus Christ. The Church Age began at Pentecost and ends at the Rapture. Seals began at the merger of Church and Roman State. Trumpets began with World War I. The Tribulation begins with a seven year covenant and World War III. The reign of the unholy trinity of Satan, Antichrist and False Prophet begins half way through the Tribulation. World War IV and the bowls follow. Seals, trumpets, Tribulation, reign of Antichrist, bowls and Armageddon end at the Second Coming. Since we are about one hundred years into the Laodicean period, four horses are on the run and five trumpets sounded before the Tribulation. The beginnings of three world wars are falling into place. We are ~1990 years into the End Times and see Revelation being fulfilled.
