Though born innocent (see D&C 93:38), all men, through the fall of Adam, are born into a fallen world. Knowing good and evil (see Moses 4:11, 5:11) and living in this imperfect state, all men sin (see Romans 3:23, 1 John 1:8–10) and experience a resultant “fall” and spiritual death (see Moses 6:49, 55, Alma 42:9). In other words, it is through transgression of God’s law that one becomes a “natural man” (see Mosiah 16:2–3, Alma 42:10–12, D&C 20:20). Hence, a natural man is an enemy to God until he qualifies for the cleansing influence of the Atonement by living the commandments of God (see Mosiah 3:11–12, 19). Man then becomes a new creature, being born again, and becoming spiritually alive (see John 3:3–8, Mosiah 27:25–26) and worthy to be known as a friend of God (see John 15:14).
