According to McConkie and Millet, the expression "Spirit of the Lord" is used some forty times in the Book of Mormon, and almost without exception it has reference to the Holy Ghost or to the Light of Christ. If indeed here in 1 Nephi 11:11 the Holy Ghost was Nephi's guide and teacher, this occasion is of tremendous significance, for it is the only scriptural occasion wherein the Holy Ghost makes a personal appearance to man.
