When we talk about the plan of salvation, as Teachings of the Presidents of the Church: Joseph Fielding Smith lesson #3 does, we focus on several key elements: the pre-existence, the fall, the atonement, the resurrection and the judgment. That’s a lot of ground to cover—and often our lesson manuals cover each of those elements separately. Likewise, it is difficult to come up with a single poem that covers all of this territory. But Elder Orson F. Whitney, who served as an Apostle from 1906 to 1931, seemed to love writing poetry about the gospel and the plan of salvation, producing several works that covered this same territory.
The final lesson for the Book of Mormon Gospel Doctrine class covers Moroni 7-10, the final Book of Mormon prophet’s closing advice to readers, including teachings about faith, hope and charity, the conditions of salvation, spiritual gifts, the role of the Holy Ghost, and how to judge between good and evil. The motivation for this latter counsel is somewhat captured in this poem, which looks at the extremes to which our friends can sometimes push us, and the feeling of being lost or torn between opposites that can happen if we try to follow their advice.
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.
