Isaiah 34:1-2. “Come near, ye nations, to hear; and hearken, ye people: let the earth hear, and all that is therein: the world, and all things that come forth of it. For the indignation of the Lord is upon all nations, and His fury upon all their armies: He hath utterly destroyed them, He hath delivered them to the slaughter.”
The nations who hate Israel, and who have cooperated with Antichrist, will be called to account. This entire chapter is far future, unfulfilled until after the Great Tribulation and Armageddon, when God will pour out His wrath on those nations who have persecuted Israel.
Here are some other scriptures passages that talk about this same event:
Joel 3; Zech. 14:1-5; Rev. 16:13-16; 19: 11-21.
Some may ask, “How can a loving God be so angry, and destroy so many people?” The answer is clear all through the prophecies of the Old Testament. Over and over, God used the prophets to warn His own people, the Jews, to turn from their idols and repent, and be restored. The Gentile nations were also warned that those who harmed His people, Israel, would suffer His wrath.
Finally, after so many thousands of years, God will have had enough. The time will come for His plan and purpose to take place. He is neither unloving nor unjust. He has been patient, but the nations have ignored Him and persisted in their efforts to destroy His people.
