20. Verse 3 And God said, Let there be light; and there was light. This is at the outset when a person starts to realize that good and truth are something superior. Thoroughly external people do not even know what good is and what truth is, for they imagine that everything which comprises self-love and love of the world is good, and that everything that panders to those loves is truth. Thus they do not know that the things which they imagine to be good are in fact evil, and that those which they imagine to be true are in fact false. But when a person is conceived anew, first he starts to recognize that the good in him is not really good, and then, when he enters more into light, to recognize the existence of the Lord and that the Lord is good and truth themselves. The Lord Himself says in John that men ought to know He exists,

Unless you believe that I am, you will die in your sins. John 8:24.

The point that the Lord is good itself, which is life, and truth itself, which is light, together with the consequent point that no good or truth exist except from the Lord, is made once more in John,

In the beginning was the Word, and the Word was with God, and the Word was God. All things were made through Him, and without Him was not anything made that was made. In Him was life, and the life was the light of men, and the light shines in the darkness. He was the true light that enlightens every man coming into the world John 1:1, 3-5, 9.

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.
