57. This is why angels are not angels in their own right but are angels by virtue of their union with the Divine-Human One; and their union depends on their acceptance of what is divinely good and what is divinely true. What is divinely good and what is divinely true are God, and seem to emanate from him even though they are within him. Their acceptance depends on the way angels apply the laws of his design, which are divine truths, to themselves, using their freedom to think and intend according to their reason, a freedom given them by God as their own possession. This is what enables them to accept what is divinely good and divinely true in apparent autonomy; and this in turn is what makes possible the mutual element in their love, for as already noted [48], love is not real unless it is mutual. It is the same with us here on earth.

All this enables us finally to see that everything in the created universe is a vessel for the divine love and wisdom of the Divine-Human One.

90. Since angels are spiritual beings, they cannot live in any warmth or any light that is not spiritual. We, on the other hand, cannot live in any warmth or any light that is not physical. This is because what is spiritual suits what is spiritual, and what is physical suits what is physical. If angels were to depend on physical warmth and light to even the least extent, they would be destroyed. It is absolutely wrong for their life.

Each of us is a spirit, as far as the inner levels of our minds are concerned. When we die, we leave this world of nature completely behind. We give up everything it has to offer and enter a world that contains nothing proper to the world of nature. In that world we live so completely distanced from nature that there is no communication along a continuum, that is, nothing like degrees of purity or coarseness. It is a case of before and after, with no communication except by correspondences.

It stands to reason, then, that spiritual warmth is not a purer form of physical warmth, that spiritual light is not a purer form of physical light, but that they are completely different in essence. Spiritual warmth and light derive their essence from a sun that is nothing but love, a sun that is life itself, while physical warmth and light derive their essence from a sun that is nothing but fire, containing no life whatever, as I have already stated [89].
