King Benjamin clearly defined the consequences of sin (see Mosiah 2:36–40). When a person knows what is right and does not do it, he not only violates the actual law but also puts himself in a state of opposition to God. This person becomes “an enemy to all righteousness” (v. 37), one of the problems of the natural man (see Mosiah 3:19).The testimony of King Benjamin and of all the prophets is that one really serves himself as he serves the Lord. Sin leads to misery, suffering, and loss of agency (see 2 Nephi 2:27–29, Alma 41:10, D&C 19:15–20).
