Benjamin is not teaching that men are depraved. We are the offspring of God and inherit both body and spirit from him.
We sustain the doctrine of the Psalmist who wrote: “Ye are gods; and all of you are children of the most High” (Psalms 82:6). Ours is a divine nature. Yet ours is a world of sin, a world in which “sin conceiveth in [our] hearts” (Moses 6:55), a world in which “all have sinned, and come short of the glory of God” (Romans 3:23).
Such is the state of the natural man, one in which he is unworthy of the divine presence. To the extent that we resist the enticings of the Spirit we are at odds with God and in a state of rebellion against that which is divine within us, “They are of the world: therefore speak they of the world, and the world heareth them” (1 John 4:5).
When men or women love Satan more than God, when they give themselves up to sinful practices, they are carnal, sensual, and devilish-natural men (see D&C 20:20; Moses 5:13).
