“Then Moses took the blood from the basins and splattered it over the people, declaring, ‘ Look, this blood confirms the covenant the Lord has made with you in giving you these instructions.'” (Exodus 24:8, NLT).
After God had given the terms of the covenant to Moses, Israel agreed to its terms (vs. 3), which was then ratified in several ceremonial activities. These activities included the formal writing and reading of the covenant (vs. 4, 7), the splattering of blood (vs. 6), a covenant meal (vs. 11), and the appearing of the glory of the Lord on the mountain (vs. 15).
“For the accuser of our brothers has been thrown down, who accuses them day and night before our God. And they have conquered him by the blood of the Lamb and by the word of their testimony, for they loved not their lives even unto death” (Revelation 12:10-11, ESV).
Some people try to turn the source of evil in the world, Satan, the devil, into a fairy tale. But, the Bible makes it clear that he exists and that he hates those who have been saved by the blood sacrifice of Jesus dying on the cross. He hates Christians so much that he accuses them before God 24/7.
“He takes away the first to establish the second” (Hebrews 10:9, HCSB).
The Hebrews writer explains how the sacrifice of Christ on the cross replaced the Old Testament system of blood sacrifices and burnt offerings.
The Hebrews writer says that the Old Testament law was a representation of God’s reality, not the reality itself: “The law has only a shadow of the good things to come, and not the actual form of these realities” (vs. 1).
“And if any native Israelite or foreigner living among you eats or drinks blood in any form, I will turn against that person and cut him off from the community of your people, for the life of the body is in its blood. I have given you the blood on the altar to purify you, making you right with the Lord. It is the blood, given in exchange for a life, that makes purification possible.”
These verses explain the theology of substitutionary atonement.
Israel was forbidden to consume blood because blood was symbolic of the life given by God and was reserved as God’s portion of each animal sacrifice.
God had also designated the sacrificial blood as the means of atonement. In other words, God’s grace permitted the life of the animal to be a substitute in exchange for the life of the human sinner.
The sacrifice of Christ on the cross follows this same pattern for substitutionary atonement as described in Leviticus with the exception that Christ’s sacrifice, because He was God Incarnate, was once and for all while the sacrifice of bulls and goats had to be made repeatedly.
