In Hebrews 9:23-28 the author explains the cleansing power of Christ’s blood. Pastor Grasso explains the distinction between propitiation and expiation to understand these two elements of the atonement. Propitiation is the satisfaction of God’s wrath. Expiation is cleansing from sin. Christ’s blood, however, has a cosmic element to its cleansing. As Adam’s fall resulted in the world being subject to corruption, so too, in Christ’s death, the world is cleansed so as to bring forth a new creation.
