Revelation 18:1-3: How are the mighty fallen?
After this I saw another angel coming down from heaven. He had great authority, and the earth was illuminated by his splendour. 2 With a mighty voice he shouted:
‘“Fallen! Fallen is Babylon the Great!”
She has become a dwelling for demons
and a haunt for every impure spirit,
a haunt for every unclean bird,
a haunt for every unclean and detestable animal.
3 For all the nations have drunk
the maddening wine of her adulteries.
The kings of the earth committed adultery with her,
and the merchants of the earth grew rich from her excessive luxuries.’ NIV
‘We shall see John’s own vision of this ideal city at the end of the book. But for the moment we are shown its opposite: the city which tried, like Babel of old, to make itself The Place, the summit of human achievement, by its own efforts and to its own glory – and ends up shrinking to a shell, with the wild desert creeping back into its palaces, its temples, its fine streets and shops and courtyards. Creation will reclaim what arrogant humans had thought to construct. Babylon will become a place for demons, for unclean spirits, for birds and monsters of all the wrong kinds. And this, John says, is good news – just as the destruction of Babel, and the confusion of tongues (Genesis 11) was good news. The angel who shouts out that Babylon has fallen (echoing Isaiah 21.9 and Jeremiah 51.8) is bringing the news that human arrogance and oppression, and the wanton luxury and vice to which they lead, will not have the last word. God will have the last word, and creation itself will hear this word as a word of freedom, a sigh of relief, a flood of glorious light (verse 1) let in upon a darkened dungeon.’ Tom Wright: ‘Revelation for Everyone’, p.159.
It is important for us to grasp that this all-pervasive world system, spoken of as ‘Babylon’, has limited time. It will fall.
