Revelation uses the word “city” ( polis ) 28 times, that is, 4 x 7. The city is the four-cornered world through the seven days of the creation week.

In the history of that world city, the new Jerusalem comes to dominate John’s closing vision. Fittingly, 12 uses of polis are in Revelation 21-22.

The history of the world city climaxes in the city of Israel, the new Jerusalem that descends from heaven.
