Of all the Old Testament images that foreshadow Jesus, the Passover lamb was perhaps the clearest in foreshadowing Jesus’ saving work at Calvary. According to God’s own appointment, God promised to remove His judgment from His people when He saw the substitutionary blood of a spotless lamb painted on the doorposts of the Israelites’ homes in Egypt. The Passover was a sign of God’s covenant with His people in the Old Testament, indicating the way in which He would one day satisfy His wrath through the sacrifice of Christ.
