"We clean our garments by washing them in water. Filth, dirt, germs, odors, and whatever is unclean and offensive is thus removed; our wearing apparel becomes clean and spotless. A saved person is one whose soul is clean and spotless, one who is free from the filth and corruption of sin; and the prophetic way of describing such a person is to say that his garments are clean. Since the only way a human soul can be cleansed and perfected is through the atonement of Christ, it follows that the symbolic way of describing this process is to say that such a one has washed his garments in the blood of the Lamb, as we have here learned Nephi and Alma did." (The Promised Messiah: The First Coming of Christ, p. 251.)
