“Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning” (James 1:17).

God, Himself, is both author and finisher of everything we have that is good. This, of course, is the testimony concerning His creation in the beginning, which was both “very good,” and “finished” (Genesis 1:31; 2:1). The unique name “Father of lights” seems to suggest a remarkable scientific insight. Since light is the most basic form of energy, and yet is equivalent also to all other forms, and since literally everything in the physical universe is energy in some form, it is singularly appropriate to speak of the totality of all God’s good and perfect gifts in creation as “lights.” And, since all these energies are not now being created (only “conserved”), their original source can only be from the Father of lights!

There even seems to be a hint of both of the two great laws of science here: energy conservation as well as energy deterioration. The term “variableness,” used only here, means literally “transmutation.” Just as God is immutable, the total amount of His created “lights” is conserved—neither created nor destroyed. The Second Law states that, in all energy conversions (that is, in everything that happens), the entropy of the universe increases. “Entropy” means “in-turning,” coming from two Greek words, en and trope—the second of which is used in this verse. Entropy is a measure of disorganization, and its inexorable increase is a result of God’s curse on the creation following man’s rebellion. Thus, although the total energy of the universe is conserved (by the First Law), the available energy is decreasing (by the Second Law). Nevertheless, God Himself is not bound by this law which He has imposed, for a time, on His creation. With Him is not even a "shadow" of any "turning" (trope).  God never changes, and His purposes can never be defeated! HMM
