Leviticus 17:11—For the life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul.
Blood brings life-giving oxygen and nutrients to every cell in our bodies. It carries away the waste from every cell. Without this wonderful process of both bringing nutrition and carrying away waste, we quickly die. Our brains cease to function after only a short time without sufficient blood flow. Truly, blood is our physical life. God told Moses that the reason He designed us this way was so that the blood could make atonement for us on the altar. It makes atonement or covering for our sins. As the priest would slay the once- a- year atonement sacrifice, he would gather the blood to sprinkle before the Ark of the Covenant where God dwelt. The blood brings life, and the blood takes away impurity. Man’s rebellion against God is so serious that only death is a sufficient penalty. Since life is in the blood, blood must be spilled as justice. From the foundation of the earth, God determined that it would be the blood of His own Son. That was the only blood that could take away the impurity of the world. All other blood was insufficient to remove sin. They had their own sin that needed to be removed. The blood of animals could cover for a time (atonement) until the sufficient blood was shed, the blood acceptable to God for the sins of the world. Thank God today that He made a way to do what you could never do. Without the blood of Jesus, there would be no hope for the removal of the impurities of your life. Like a person with liver failure, you would have died on your own poisons. But the blood of Christ cleanses us from all sins.
