Great Cities.
Today we might say Moscow, New York, Shanghai, Paris and London and there a quite a few more? We remember them because they are the seats of great power, freedoms, liberation, culture, science, all the attributes of human achievment!
The bible tells us to about the great cities that hold dark powers, these are the ones that oppress humanity, who murder believers in the past, today and the future.
God tells us through His word how he has destroyed those early ones with water and how one new one will be for all who had faith in Jesus, after the whore is destroyed.
Genesis 4:17, Luke 17:27-28, Revelation 14:8, 21:2.
Ask me and I will tell you!
