DISASTERS FROM THE FOUR ANGELS
Revelation 8.7-13
If we look at the disasters brought by the angels, the disaster are all similar in some ways to the disasters inflicted on Egypt during the Exodus. When GOD lead His people through the desert and gave them the Law (the Law of Moses) He set Conditions by promising them blessings for obedience and curses for disobedience (Curses of Egypt: Deuteronomy 28.27.60).
In similar ways GOD punish the nations of the world for their refusal of Him and for their abominations, and for His people Israel which the nations of the world brutally treating and wanted to wipe out the people of GOD from the face of the Earth.
Eventually after all these disasters the nations of the Earth will submit themselves to the will of GOD and will make pilgrimage every year to the Holy Land and will be forced by GOD to observe even Holiday of Booths (Zechariah 14.16-21), which is also a Statute of the Law of Moses.
~ Nations will come to Zion and will worship the Lord the GOD of Israel: (Isaiah 14.1, 18.7, 19.19-23, 55.5, 60.3.6-7.9-13.16, 66.23) (Jeremiah 3.17) (Zechariah 2.11, 8.22, 14.16-21) (Revelation 11.6-13, 15.4).
~ 11. *Wormwood. A bitter, aromatic herb (Artemisia judaica L.) which clusters of small, greenish yellow flowers and alternating greenish gray leaves, growing in desert areas. Related to our sagebrush, the wormwood is the source of an essential oil obtained from the dried leaves and the tops of the plant. Five species are known to exist in Israel. The plant was a symbol of bitterness, embodying the hardship and evil of life (Proverbs 5.4) (Lament 3.15.19) (Amos 5.7. KJV, NIV "gall, bitterness"; Revelation 8.11).
The New International Dictionary of the Bible. J. D. Douglas, Merrill C. Tenney.
~ GOD punish disobedient individuals and nations sometimes directly and sometimes by different cataclysms of nature. Many of us already noticed changes in weather and forces of nature what brings disasters. They are not accidental and not driven by unexpected chain of events, in part it all due to our own neglect of the Rules what GOD established for carrying and cultivation of the land on which we live, and also due to our own rejection of GOD'S morality and His Statutes on which blessing and prosperity take effect for those who obeying His Laws.
But the worst has not come yet and humanity will learn its lesson sooner or later.
