The book of Hebrews instructs us that Christ is both priest and sacrifice. He makes the perfect offering of himself to God on behalf of our sin. This priestly activity is rooted in the Old Testament activity of worship. At the cross the Lord Jesus is at worship. He is honoring the Father through his perfect obedience and his blameless sacrifice. His life was a life of worship and at the cross his worship reaches a crescendo. It is an astonishing thing to view the cross as a pure act of worship. Christ offers his body as a sacrifice—this is his pleasing and acceptable expression of worship. It was this expression of worship that saved you and me.
