The next day John saw Jesus coming toward him, and said, “Behold! The Lamb of God who takes away the sin of the world” (John 1:29).
In many ways, the Old Testament is like the “storybook” of the New Testament. The Old Testament reveals in pictures the truths of the New Testament.
Blood, for example, is a symbol of life in the Scriptures (Leviticus 17:14). God prescribed for the Jews a long-list of sins for which the blood sacrifice of an animal was required. Yet despite all those sacrifices under the Old Covenant, animal blood never forgave a single sin. Those Jewish sacrifices were given to point Israel to the need for a better, a Perfect Sacrifice which the Father would make by His Son.
Redemption has always depended upon the Lamb provided by God rather than a lamb provided by the sinner. Only the blood of Jesus removes sin and sin’s stain.
For it is not possible that the blood of bulls and goats could take away sins. Not with the blood of goats and calves, but with His own blood He entered the Most Holy Place, once of all, having obtained eternal redemption (Hebrews 10:4; 9:12).
