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!

When the Bible speaks of "Jehovah," it is representing love itself, the inmost love that is the essence of the Lord. That divine love is one, whole and complete in itself, and Jehovah also is one, a name applied only to the Lord. The divine love expresses itself in the form of wisdom. Love, then, is the essence of God -- His inmost. Wisdom -- the loving understanding of how to put love into action -- is slightly more external, giving love a way to express itself. Wisdom, however, is expressed in a great variety of thoughts and ideas, what the Writings collectively call divine truth. There are also many imaginary gods, and sometimes angels and people can be called gods (the Lord said Moses would be as a god to Aaron). So when the Bible calls the Lord "God," it is in most cases referring to divine truth. In other cases, "God" has reference to what is called the divine human. The case there is this: As human beings, we cannot engage the Lord directly as divine love. It is too powerful and too pure. Instead, we have to approach Him by understanding Him through divine truth. Divine truth, then, is the Lord in human form, a form we can approach and understand. Thus "God" is also used in reference to this human aspect, because it is an expression of truth.
