Here are some excerpts from Swedenborg's "Arcana Coelestia" that help explain the inner meaning of this chapter:

AC 3656. In the supreme sense this chapter treats of the Lord, how He began to make His natural Divine both as to truth and as to good; and the means by which He effected this are described in general. But in the representative sense it treats of how the Lord regenerates or makes new the natural of man both as to truth and as to good; the process in general is in like manner described (verses 1 to 10).

AC 3657. In the internal supreme sense there is described how the Lord began to make His natural Divine as to truth from the ultimate of order, that thereby He might make disposition of the intermediates, and might conjoin each and all things with the First; that is, with His Divine Itself. But in the internal representative sense there is described how the Lord regenerates the human natural also from the ultimate of order, and thereby disposes the intermediates, in order that through the rational He may conjoin them with Himself (verses 11 to 22).

3657. Described in the highest sense is the way in which, starting from the lowest degree of order, the Lord began to make Divine the truth of His Natural, so that He might thereby set in order intermediate degrees and link every single one to that which is the First, that is, to His own Divine. But the internal representative sense describes the way in which, again starting from the lowest degree of order, the Lord regenerates the natural in man and thereby sets in order intermediate degrees, so that through the rational He may join these to Himself, verses 10-22.
