“Abraham is the rock, and Sarah is the quarry. We must live up to the covenant called after Abraham. Ultimately, the covenant is centered on the Rock of our Salvation, which is Jesus Christ. Just as a rock will have the same physical properties and composition as the mountain from which it is taken, so we have the potential to become like our Father and his Son, our only sure foundation” (Ogden and Skinner, Book of Mormon, 1:142).
