Why is the shedding of blood important in redemption?

According to Hebrews 9:22, 'without the shedding of blood there is no remission.' This principle is rooted in both the Old and New Testaments, highlighting that blood signifies life and is essential for atonement. In the sacrificial system established in the Old Testament, blood was a necessary component to cover sins, pointing forward to the once-for-all sacrifice of Christ. His blood, shed on the cross, serves as the ultimate atonement for sin, satisfying God's justice while manifesting His grace and mercy. Through this sacrifice, believers find forgiveness and are redeemed from the bondage of sin, entering into a restorative relationship with God.
