The priesthood of Christians. In these final exhortations, the preacher explains in detail what the life of Christians should be, viewed as genuine worship of God. These are not merely moral advice that could fit at the end of any sermon. The preacher encourages his listeners to become priests like Jesus, meaning to participate in his priesthood of unwavering devotion to God and service to others through their personal commitment. The kind of worship God desires is this kind of sacrifice: self-giving. Therefore, the responsibilities of this priesthood for the faithful are centered on life rather than on worship.
