This is Mormon’s most concise statement of the purpose for which he wrote his work that we have as the Book of Mormon. His entire purpose is to “persuade all… ends of the earth to repent and prepare to stand before the judgment-seat of Christ.” In particular, his eschatological sense of his work was that it would be a harbinger of the end-time events. He was quite cognizant that the Messiah would come again, and it is no mistake that he highlights in this statement the need for us to stand before this Messiah.
Textual: This is the end of a chapter in the 1830 edition.
