The significance of blood in the Bible and Christianity

Question: “Why did the sacrificial system require a blood sacrifice?”

Answer: The whole of the Old Testament, every book, points toward the Great Sacrifice that was to come—that of Jesus’ sacrificial giving of His own life on our behalf. Leviticus 17:11is the Old Testament’s central statement about the significance of blood in the sacrificial system. God, speaking to Moses, declares: “For the life of a creature is in the blood, and I have given it to you to make atonement for yourselves on the altar; it is the blood that makes atonement for one’s life.”

A “sacrifice” is defined as the offering up of something precious for a cause or a reason. Making atonement is satisfying someone or something for an offense committed. The Leviticus verse can be read more clearly now: God said, “I have given it to you (the creature’s life, which is in its blood) to make atonement for yourselves (covering the offense you have committed against Me).” In other words, those who are covered by the blood sacrifice are set free from the consequences of sin.

Question: “What was the significance of the sprinkling of blood?”

Answer: In Exodus 24we read of Moses sprinkling blood as an important part of a ceremony commanded by God. The context shares part of the reason for this ritual:

[Moses] got up early the next morning and built an altar at the foot of the mountain and set up twelve stone pillars representing the twelve tribes of Israel. Then he sent young Israelite men, and they offered burnt offerings and sacrificed young bulls as fellowship offerings to the Lord. Moses took half of the blood and put it in bowls, and the other half he splashed against the altar. Then he took the Book of the Covenant and read it to the people. They responded, “We will do everything the Lord has said; we will obey.”

Moses then took the blood, sprinkled it on the people and said, “This is the blood of the covenant that the Lord has made with you in accordance with all these words.”(verses 4–8)
