As already noted [Section 65], heaven is divided into as many communities as there are organs, viscera, and members in us, and no part of these can be anywhere except where it belongs. Since angels are parts like this in the divine heavenly person, then, and only people who have lived on earth become angels, it follows that people who allow themselves to be led to heaven are constantly being prepared by the Lord for their places.
This happens by means of the kind of desire for what is good and true that corresponds, and every angel-person is enrolled in this place after leaving our world. This is the very core of divine providence in respect to heaven.
