What are some of the things we get from the Book of Mormon

"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 Nephi 9:28-29).

From the Book of Mormon we learn about:

• The plan of salvation or "the great plan of happiness" (Alma 42:8; Alma 42:5. 8. 12. 30)
• The doctrine of Christ and the Atonement (2 Nephi 31:2-21; 32:1-6; 3 Nephi 11:31-40; 27:13-21).
• Why death is necessary (2 Nephi 9:4-6; Mosiah 16:8-9; Alma 12:25-27).
• Life after death in the spirit world (Alma 41:11-14).
• The workings of the evil one (2 Nephi 2:27; Alma 28:13; 3 Nephi 2:2).
• The order of the priesthood (Mosiah 29:42; Alma 4:20; 5:3, 44; Alma 13:1-10).
• Sacramental prayers (Moroni 4:3; 5:2).
• A sure way to judge between good and evil (Moroni 7:16).
• How to retain a remission of your sins (Mosiah 4:26)"
