If the Lord were not in control of both the heavens and the hells, there would be no equilibrium; and if there were no equilibrium, there would be no heaven or hell. Absolutely everything in the universe, everything in both the natural world and the spiritual world, is constituted by an equilibrium. Any rational person can grasp this. Let one side outweigh the other, with no resistance offered, and will not both be destroyed? This is what would happen in the spiritual world if the good did not react against the evil and constantly suppress its rebellions. Unless the divine power, and nothing else, did this, heaven and hell would perish, and the whole human race along with them. I refer to the “divine power and nothing else” because the selfhood of every angel, every spirit, and every one of us is nothing but evil (see above, Section 591). This means that no angel or spirit can ever resist the evil influences that are constantly breathed out of the hells since we all incline toward hell because of our self-concern. We can see from this that if the Lord alone were not in control of both the heavens and the hells, there would be no salvation for anyone.
Not only that, all the hells act in unison because the evil energies of the hells are all interconnected the way the good energies are in the heavens; and nothing but the only divine power can resist all the countless hells acting in concert against heaven and everyone there. That one divine power emanates from the Lord.
The balance point between the heavens and the hells shifts down and up depending on the number of people entering heaven and entering hell, which amounts to thousands every day. Knowing and grasping this, adjusting and centering the pointer of the scales, is something no angel can do, only the Lord, since the emanating divine nature is everywhere present and is everywhere watching every deviation. Angels see only what is around them, and do not even sense within themselves what is happening in their own community.
Everything in the heavens and the hells is so arranged that each individual there is in a personal equilibrium. We can to some extent gather this from what has already been presented concerning the heavens and the hells. That is, all the communities of heaven are very precisely differentiated according to the genera and species of their goodness, and all the communities of hell according to the genera and species of their evils. Further, there is a corresponding community of hell underneath every community of heaven, and this opposing correspondence yields an equilibrium. So the Lord is constantly making sure that the hellish community under any heavenly one does not get too strong. To the extent that one begins to get too strong, it is brought under control by various means and returned to its proper balanced relationship. I shall mention only a few of the many means. Some involve a stronger presence of the Lord. Some involve closer communication and union of one or more communities with others. Some involve the exile of extra hellish spirits into desert places, some the transfer from one hell to another, some the reorganization of the people in the hells, which also is accomplished in various ways. Some involve concealing some of the hells under thicker and heavier coverings, some sending them down deeper. Then there are other means, some involving the heavens overhead.
I mention this so that there may be some grasp of the fact that only the Lord provides that there shall be a balance between good and evil everywhere, and therefore between heaven and hell. On this kind of equilibrium depends the salvation of everyone in the heavens and everyone on earth.
