For the life of the flesh is in the blood, and I have given it to you upon the altar to make atonement for your souls; for it is the blood that makes atonement for the soul
God instituted animal sacrifice to make atonement for the sinful souls of humanity in the Old Testament, but a river of blood from bulls, rams, goats, and turtledoves could not save us.
Christ alone redeemed us from the curse of the Law through the shedding of His blood (Galatians 3:13)! Only His blood could atone for us. We are not redeemed with perishable things like silver or gold or the dead-end traditions of the past. No! We were bought with the priceless blood of the perfect Lamb (I Peter 1:18-19). The Innocent died so the guilty could go free!
In our physical bodies, bones, muscles, organs, tendons, and nerves are set in place. The blood, though, is ever moving. It circulates through the body about every 20 seconds carrying oxygen, nutrients, and cleansing power. Life is in our blood. When a nurse touches our wrists, she is looking for the pulse created by moving blood. No pulse indicates death.
In the body of Christ, His blood circulates to give us life, to connect and empower us individually and corporately. Without His blood, we can expect deprivation and death. True life is found only in the blood of Jesus.
