Ezek 45: The picture of the shed blood begins in Exodus as a picture of God’s overarching protection. Ezekiel is told that in the future, the priests will reinstitute that practice, and it mirrors that of Exodus 12, where the angel of death would see the shed blood and pass over the household on the night of the last plague where the death of the firstborn of Egypt would be taken. The Hebrews author reminds his audience that without the shedding of blood, there is no forgiveness. [Heb 9:22] Christ was the completed fulfillment of this when He shed His blood on the cross for the payment of our sins.
If Christ fulfilled this through the shedding of His blood, why then is it then reinstituted? Perhaps to remind us of our sinfulness and the price that had to be paid. Surely, this should stop us and remind us of the night in which He was betrayed. He then said: “this is the cup of the new covenant in my blood. Do this, every time you drink of it in remembrance of me.” [1Cor 11:25] Take heed, beloved, as you partake and seek cleansing of your sins and the price paid
