“Just as the Sermon on the Mount begins on a mountain, it ends by talking about the wise man who builds upon that mountain, by not only hearing but actually patterning his house of righteousness after God's holy house. Progressively, through these stages of ascent, there comes first fulfillment of the law amidst the people of Israel, next perfection of each individual, and finally hearing the Lord himself say, "Enter," not "Depart" (3 Nephi 14:21-23). ”
