557. "Therefore rejoice, O heavens, and you who dwell in them!" (12:12) This symbolizes the new state of heaven, that the inhabitants are in the Lord and have the Lord in them.

The heavens mean the heaven formed of Christians in which the Lord alone is acknowledged as God of heaven and earth. The injunction to rejoice symbolizes its new state, one full of joy. The inhabitants symbolize people who are impelled by goodness (no. 380), and since all goodness comes from the Lord, it means, symbolically, that they are in the Lord and have the Lord in them.
