Written to demonstrate how Jesus perfects the priesthood, rituals, and sacrifices of ancient Israel, Hebrews shows us the dignity of Christ's humanity and the majesty of his divinity, presenting him as the one priest and the perfect sacrifice of the new covenant. Through Jesus our mediator, we learn how to satisfy our anxious longings, remove the barriers that sin erects, join our lives to God's all-holy presence, and participate in the heavenly worship of God.
