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.

741. That 'Noah went into the ark from before the waters of the flood' means that he was protected may become clear to anyone. Temptations are nothing other than conflicts between evil spirits and angels who reside with a person. Evil spirits activate all the dishonourable things the person has done or even thought which have been with him since early childhood, thus both evils and falsities; and in so doing, the spirits condemn him, for nothing gives them greater delight. Indeed the very delight of their lives consists in doing just that. But the Lord protects the person by means of angels and prevents the evil spirits and genii from overstepping the mark and overwhelming him with more than he can cope with.
