Your authority comes through your ordination; your power comes through obedience and worthiness. Power in the priesthood comes from doing your duty in ordinary things: attending meetings, accepting assignments, reading the scriptures, keeping the Word of Wisdom. President Woodruff said: "I traveled thousands of miles and preached the Gospel as a Priest, and, as I have said to congregations before, the Lord sustained me and made manifest His power in the defense of my life as much while I held that office as He has done while I [hold] the office of an Apostle. The Lord sustains any man that holds a portion of the Priesthood, whether he is a Priest, an Elder, a Seventy, ... an Apostle, if he magnifies his calling and does his duty."
