In these two chapters, 15 & 16 of Revelation, we find the seven angels with the seven last plagues full of God's wrath. Before the 7 golden bowls of wrath are poured out, the ones who had been victorious over the beast, his image, and the number of his name (the unholy trinity), worshiped the Lord by singing, "The song of God's servant Moses, and the song of the Lamb." God's glory filled the temple, and then came God's undiluted wrath on those who worshipped the beast. Many of these plagues mimic the plagues God brought upon the Egyptians with Moses. God's wrath is not due to vengeance, but for justice, because they had shed the blood of the saints and the prophets. Chapter 16 verse 15 gives the third beatitude found in Revelation, "Behold, I am coming like a thief. Blessed is the one who stays awake and keeps his clothes, so that he will not walk about naked and men will not see his shame." The people still do not repent, and it all builds up for war against God. Verse 16 described the place where they gathered as "Har-Magedon." Needless to say, God won and "Babylon" fell because God remembered.
