The document discusses the roles of priests in ministering before God. Faithful priests like Zadok were allowed to minister in the outer court, holy place, and holy of holies. In contrast, unfaithful priests like Eli and Abiathar were confined to the outer court only. True worship requires living a holy life and being vessels prepared for noble purposes. Proper order is needed when carrying God's presence, as the faithful priests will one day see God face to face in heaven.
