862. That 'it happened at the end of forty days' means the duration of the former state, and the beginning of the one that followed, is clear from the meaning of 'forty', see 730, where, the subject being temptation, the phrase 'forty days and forty nights' was used, which meant the duration of temptation. Here, since the subject is the state following temptation, 'forty days' is mentioned but not forty nights. The reason is that charity now starts to appear, which in the Word is compared to the day and is called the day. Faith however which precedes but has not yet been so joined to charity is compared to the night and is called the night, as in Genesis 1:16, and elsewhere in the Word. Faith is also called 'the night' in the Word because it receives its light from charity, just as the moon does from the sun. Faith is therefore also compared to the moon and is called the moon; and love or charity is compared to the sun and is called the sun. 'Forty days', or the duration of time meant by them, refers both to the things that precede and to those that follow; hence the statement 'at the end of forty days', which accordingly means both the duration of the previous state, and the beginning of the one being described now. This then begins the description of the second state following temptation of the member of this Church.

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.
