The Book of Mormon is an endless treasure of wisdom and inspiration, of counsel and correction, “adapted to the capacity of the weak and the weakest [among us]” (D&C 89:3). At once, it is rich in nourishment for the most learned, if they will humble themselves (see 2 Ne. 9:28–29).
From the Book of Mormon we learn about:
The plan of salvation or “the great plan of happiness” (Alma 42:8; see also Alma 42:5, 8, 12, 30).
The doctrine of Christ and the Atonement (see 2 Ne. 31:2–21; 2 Ne. 32:1–6; 3 Ne. 11:31–40; 3 Ne. 27:13–21).
Why death is necessary (see 2 Ne. 9:4–6; Mosiah 16:8–9; Alma 12:25–27).
Life after death in the spirit world (see Alma 40:11–14).
The workings of the evil one (see 2 Ne. 2:27; Alma 28:13; 3 Ne. 2:2).
The order of the priesthood (see Mosiah 29:42; Alma 4:20; Alma 5:3, 44; Alma 13:1–10).
Sacramental prayers (see Moro. 4:3; Moro. 5:2).
A sure way to judge between good and evil (see Moro. 7:16).
How to retain a remission of your sins (see Mosiah 4:26).
Clear, prophetic warnings and many, many other things pertaining to the redemption of man and to our lives. All are parts of the fulness of the gospel (see D&C 20:9). (“The Book of Mormon:Another Testament of Jesus Christ—Plain and Precious Things,” Ensign, May 2005.)
