When we see the vast assortment of living beings, all classified into plants, animals, phylum, genus, and species, etc., we may apply that knowledge to the thoughts that live within our minds.
Just as most of the living things ourside of us are classified as being either Plants or Animals, our thoughts are of two basic kinds; one sort of thought leads us closer to God, the other leads us away from Him. Every thought we think, word we say, and deed we do reflects our increasing or decreasing distance from the God Who loves we whom He Programmed.
