One of the first incidents recorded which greatly impressed my mind and which may convey a useful lesson was related by my father. His parents, who had a large family, lived in Nauvoo and were quite intimate with the Prophet Joseph. In fact, his father, being a Master Mason, officiated in conducting the Prophet through all the degrees of masonry. In doing this the Prophet explained many things about the rites that even Masons do not pretend to understand but which he made most clear and beautiful.
