3. Without such life the Word as regards the letter is dead, for it is the same with the Word as it is with man, who, as the Christian world knows, is internal as well as external. The external man if parted from the internal man is just a body and therefore dead. It is the internal man which lives and imparts life to the external. The internal man is the soul of the external man. The same applies to the Word which as to the letter alone is like the body without a soul.

In the Word, “light” in the highest sense represents Divine Truth: knowledge, ideas, understanding that come to us from the Lord. In lesser degrees -- the light of a lamp, the light of the moon and so forth -- it represents lower levels of truth, ideas and understanding drawn from more earthly sources. Also, the sun in the Word represents the Lord, with its heat representing the divine love and its light representing the divine wisdom. That wisdom flows into our minds and enters our lives in the form of truth -- things we can know and ponder that lead us and help us to be good people. This connection between light and thought is one of many spiritual/natural relationships that's embedded in our common language. People “see the light” when they understand something; we try to “shed some light” by bringing new thoughts to a difficult question; people are “enlightened” when they get new information or a more complete understanding of something. And a light bulb in a cartoon represents an idea!
