Heaven and Hell # 80
80. Since angels do not perceive an invisible Divine Being (which they call a formless Divine) but a visible Divine Being in human form, it is common practice for them to say that only the Lord is a person, and that they are people because of him. They also say that each of us is human in proportion to our acceptance of him. By "accepting the Lord" they understand accepting what is good and true that comes from him, because the Lord is present in everything good and true that comes from himself. Angels call this wisdom and intelligence. They say everyone knows that intelligence and wisdom are what make us human, not simply the outward form by itself.
The truth of this is actually visible to angels of the inner heavens. Since the Lord keeps them engaged in what is good and true and therefore in wisdom and intelligence, they are in the loveliest and most perfect human form; while the angels of lower heavens are in a less perfect and lovely form.
Everything is inverted in hell. In heaven's light, the people who are there hardly look human at all. They look like monsters. They are caught up in what is evil and false and not in what is good and true, and are therefore in the opposite of wisdom and intelligence. As a result, their life is not called life, but spiritual death.
