In the final minutes of his visit with the Nephites (3 Nephi 27), Christ makes clear that the church established for the Nephites must bear his name and teach his gospel. He even specifies elements of his gospel: the atonement and resurrection, the final judgment, repentance, baptism, faith in Jesus Christ, the gift of the Holy Ghost and enduring to the end. I don’t think it would be very hard to connect any Mormon doctrine to this list.
I think the most significant event in Mosiah 18-24 is the baptism of Alma and his followers in the Waters of Mormon. There we find the great description of the Baptismal covenant, in which those baptized …are willing to mourn with those that mourn; yea, and comfort those that stand in need of comfort, and to stand as witnesses of God at all times and in all things, and in all places… This event led me to a poem by Parley P. Pratt about Baptism, a hymn that seeks to encourage non-members to partake of the ordinance.
While to some it may seem like “the work of salvation” is about missionary work, the Church takes a much broader view.
