What does Revelation 14:8 mean?
Another angel appears in John's vision and announces the fall of Babylon. The Bible depicts Babylon as the center of Satanic activity from the days following Noah's flood until its fall at the end of the tribulation. Babylon is notorious for its idolatry, blasphemy, and immorality. The book of Daniel reveals its idolatry in the case of Nebuchadnezzar's command to worship a giant image (Daniel 3:1–7) and its blasphemy and immorality in the case of Belshazzar (Daniel 5).Jeremiah 50:38 describes Babylon as "a land of images, and they are mad over idols." Further in Jeremiah 51:7 we read: "Babylon was a golden cup in the LORD's hand, making all the earth drunken; the nations drank of her wine; therefore the nations went mad." Babylon is used, in the Bible, both as a literal place and culture and as a symbol of a godless, wicked worldview.
In Scripture, then, "Babylon" is as much a reference to the world's ungodly and sinful nature as anything else. The Satanic system called Babylon is precisely what the beast and the false prophet promote, but it is doomed to destruction. According to Revelation 14:8 its end will be double destruction—both in this world, and in the world to come.
