The Book of Mormon sheds light on a “great mystery” located in John 10:16. In this paper, using a comparative method that traces intersecting pastoral imagery, I argue that John 10:16–18 not only refers to Jesus’s visit to the Lehites in Bountiful and the lost tribes of Israel but has a scripturally warranted covenant-connection to the emergence and dissemination of the Nephite record. Specifically, the Book of Mormon, according to the Good Shepherd (3 Nephi 15:12–16:20), effectively serves as his recognizable voice to the inhabitants of the earth across time and space. The Nephite record’s coming forth to eventually establish peace on earth was foretold by prophets such as Isaiah (Isaiah 52:7–10), Ezekiel (Ezekiel 34:23–25; 37:15–26), and Nephi (1 Nephi 13:34–37, 40–14:2; 1 Nephi 22:16–28). The value of this comparative approach is to recast our understanding of various passages of scripture, even as additional value is assigned to the Nephite record as the covenant of peace.
