1. Revelation 21:3 (ESV)
  2. Exposition

Why are the words “as their God” added?

Revelation 21:3 (ESV)

3 And I heard a loud voice from the throne saying, “Behold, the dwelling place of God is with man. He will dwell with them, and they will be his people, and God himself will be with them as their God.

The term underscores that in the new Jerusalem God will be for his people whatever a God is expected to be for his people. So the phrase sets the stage for the promises of Revelation 21:4.
