President Russell M. Nelson:
“The Book of Mormon is central to this work. It declares the doctrine of the gathering. It causes people to learn about Jesus Christ, to believe His gospel, and to join His Church. In fact, if there were no Book of Mormon, the promised gathering of Israel would not occur [see Bruce R. McConkie, A New Witness for the Articles of Faith (1985), 554]” (Russell M. Nelson, “The Gathering of Scattered Israel,” Ensign or Liahona, Nov. 2006, 80).
