18. 'The face ¹ of the deep' is that person's desires and resulting falsities, of which he consists and in which he is completely absorbed; and because he has no light at all he is like the deep, or something thoroughly obscure. Throughout the Word such people are also called 'the deep' and 'the depths of the sea' which are dried up or laid waste until a person's regeneration starts, as in Isaiah,

Awake as in the days of antiquity, the generations of long ago. Was it not You that did dry up the sea, the waters of the great deep; making the depths of the sea a road for the redeemed to go across? Let the ransomed of Jehovah return. Isaiah 51:9-11.

Furthermore, when looked at from heaven, this kind of person resembles a darkened mass with no life to it. The same expressions embody within them in general the vastation in man, described many times by the Prophets, which precedes regeneration. For before a person can know what truth is, or be moved by good, the things that hinder and offer resistance must be removed. Thus the old man must die before the new one can be conceived.

Footnotes:

Water generally represents “natural truth,” or true concepts about day-to-day matters and physical things. Since all water ultimately flows into the seas, then, it follows that a sea represents a huge agglomeration of such natural truths -- usually all of the natural truth a person has, or all the natural truth a church has. Water in the sea mixes freely, and is easily stirred up by winds and currents. This is also true of the concepts we hold about natural things -- they are not all related to each other, and when relationships do exist they usually can change without damaging the concepts themselves. Many of the concepts are easily disputed, and arguments can arise like waves on the ocean -- generally with little effect other than a mixing of waters. But the sea also offers great bounty. We draw fish from it (spiritual food), float ships (doctrinal systems) on it, bathe in it (using true concepts to purify ourselves), and the water that evaporates from it and falls as rain (purer forms of truth that can attach to desires for good) makes life possible.
