751. Therefore rejoice, ye heavens, and ye that dwell in them.- That this signifies the salvation and consequent joy of those who become spiritual by the reception of Divine Truth, is evident from the signification of rejoicing, as denoting joy on account of salvation; from the signification of the heavens, as denoting those who are spiritual (concerning which we shall speak presently); and from the signification of ye that dwell, as denoting those who live, here spiritually. That to dwell signifies to live, may be seen above (n. 133, 479, 662). The heavens signify those who are spiritual, because all who are in the heavens are spiritual, and because men who have become spiritual are also in the heavens, although they are in the world as to the body; therefore ye that dwell in the heavens means not only angels, but also men, for every man with whom the interior mind, which is called the spiritual mind, has been opened, is in the heavens, indeed, he also sometimes appears amongst the angels there. That this is so, has not been known in the world up to the present time. It must therefore be understood, that man as to his spirit is among spirits and angels, and indeed in that society of them into which he is to come after death. The reason of this is that the spiritual mind of man is formed exactly according to the image of heaven, and in such a way that it is a heaven in least form; consequently that mind, although still in the body, must nevertheless be where its form is. But this has been more fully dealt with in Heaven and Hell 51-58), where it is shown that every angel, and also every man as to his interiors, if he be spiritual, is a heaven in its least form, corresponding to heaven in its greatest form. For this reason where the Word treats of the creation of heaven and earth, the internal and external church is in general meant, and, in particular, the internal and external man, that is the spiritual and natural man. From these things it is evident that the heavens and those that dwell in them signify all who are there, and also those men who are becoming spiritual by the reception of Divine Truth in doctrine and life.

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.
