Man" is a tricky word to discuss, because the Hebrew of the Old Testament uses six different words that are generally translated as "man," with shades of meaning that are difficult to express in English. Swedenborg, meanwhile, uses two different words in the original Latin: "vir," which is a singular male person, and "homo," which usually has a meaning akin to "mankind" or "humanity" -- but is sometimes used for a singular male person as well. When used in the sense of "human" or "mankind," the meaning of "man" is based on the fact that the Lord is the perfect, divine human, and is in a way the archetype for our humanity. The Lord is, in His essence, love itself -- perfect, infinite, divine love, which is the source of all life. So in the ultimate sense, "man" represents the Lord's love and goodness. In less exalted uses, it represents the love and goodness that exists in churches, societies, and individual people. That's because the love we have, as individuals and collectively, is a reflection of the Lord's love, and our humanity is a reflection of the Lord's humanity.

The sun in the Bible represents the Lord, with its heat representing His love and its light representing His wisdom. “Daytime,” then, represents a state in which we are turned toward the Lord, receiving His love and being enlightened by His truth. And “nighttime,” obviously, represents states in which we are turned away from the Lord, left cold and blind to the truth. The most common word used for it in the New Christian theology is “obscurity.” The darkness is not absolute, of course. The light of the moon represents the understanding we can have based on facts and our own intelligence. But while the moon reflects some of the sun's light, it offers almost no heat, so this kind of understanding is a cold one, without the warmth of love. And at its darkest and coldest, night represents a state of judgment. This happens when a person -- or a church -- becomes so mired in evil and falsity that there is no light or heat. The Lord can then step in, separate the good from the evil, consign the evil to hell and begin rebuilding based on the remnant that is still good. Drastic as that sounds, it is something that we all go through repeatedly in various aspects of our loves, so that we can be rid of what is evil and let the Lord rebuild us as angels.
