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.

'The third day' as in Genesis 22:4, signifies something complete and a beginning of sanctification. 'Day,' in the Word, signifies a state, as do all references to time. When 'third' is added, it signifies the end of that state and the beginning of the following state. In the internal sense of the Word, 'three days' and 'the third day' signify the same thing. The Lord rose again on the third day, which is also why the Lord distinguished the stages of his life into three in Luke 8:32. The Lord also endured the last temptation on the cross, on 'the third hour of the day' in Mark 15:25. In Exodus 19:16, 'the third day' signifies the end of a state of preparation for reception, and so an end of purification. In Hosea 6:2, 8, 'the third day' has the same meaning as 'the seventh day,' which is a state of peace.
