Arcana Coelestia #21
21. Verses 4-5 And God saw that the light was good; and God made a distinction between the light and the darkness. And God called the light Day, and the darkness He called Night.
The light is called good, because it comes from the Lord, who is good itself. 'The darkness' is those things which were there prior to the person's new conception and birth. They were seen as light, because evil was seen as good, and falsity as truth. But in reality they are darkness and things proper to that person which are lingering on. All things that are the Lord's, being things of light, are compared to the day, and all that are man's own, being those of thick darkness, are compared to the night, as is done many times in the Word.

4796. When angels manifest themselves visually, all their interior affections are seen clearly in their faces and shine out of them, so that the face is the external form and a representative image of those affections. To have any other face than that expressing their affections is not allowed in heaven. Those who deceitfully wear any other face are expelled from that community. From this it is evident that the face corresponds to everything in general present interiorly - both to a person's affections and to his thoughts, that is, to the affections in his will and to the thoughts in his understanding. This also explains why in the Word 'face', whether a singular or a plural noun, means affections; and when it is said that the Lord lifts up His face on someone, the meaning is that out of Divine Affection belonging to His Love He has compassion on him.
