The nature of God is immortality and happiness; "He is the light and the life of the world; yea, a light that is endless, that can never be darkened; yea, and also a life which is endless, that there can be no more death." Mosiah 18:9) But, by the Fall of Adam, man's nature became carnal, that is subject to death, the opposite to God's nature. Man became mortal, or subject to the flesh. The Fall of Adam, often called the Fall of Man, is the fall from a higher plane to one of lower estate. It represents a descent from immortality to mortality; from a never-ending life where there is no death, to the bitterness and gall of a certain destruction. Being guided by fleshy desires, and being prone to suffer temptation, man in this carnal state is bound with bands strong as iron. They represent what we sometimes regard as the joys of everyday life, but they more often are the foolishness and follies of men. They bind with ever-increasing severity. Man's nature while on Earth is directly opposite to the nature of God, "and never the twain shall meet." Therefore, mortal man is without God while he endures this earthy estate. By the Fall man went contrary to "the nature of God," which nature is happiness; or went into a nature incompatible with happiness.
