'Length' symbolizes the goodness of the church for the same reason that 'breadth' symbolizes truth. This is because 'length' indicates the sweep of heaven from east to west, and 'breadth' means the sweep of heaven from south to north. Angels who dwell in the eastern and western zones in heaven are in the goodness of love, while angels who dwell in the southern and northern zones in heaven are in truths of wisdom. The same is true with the church on earth, for everyone who is in the church's goods and truths from the Word is associated with angels in heaven, and each person dwells with them in the interiors of their mind -- people in the goodness of love in the eastern and western zones of heaven, and people who are in truths of wisdom in the southern and northern zones of heaven. No one is aware of this, but everyone goes to his place after death.
