The significance of blood is found throughout the Scriptures. We find God commanding Israel not to drink the blood of animals, yet to poor it out on the altar as a substitution in the Old Testament for the forgiveness of sins so that they can be at one with God. At one, having been forgiven; sin is covered until the One comes who will shed His sinless blood for humanity. Jesus Christ, the Lamb slain for the sins of the world. His Blood shed for us to be at one with God.
