All are familiar with the use of the Liahona as a compass and director that worked upon faith. However, we sometimes forget that there were writings on the Liahona which changed from time to time. Nephi doesn't share the meaning of these writings which came directly from the Lord. He does not include them because of their spiritual and sacred nature. They were not directions to go in the wilderness, that was what the spindles were for. These writings were holy and sacred words which did give us understanding concerning the ways of the Lord (v. 29).
