Why is the shedding of blood necessary for atonement?

Hebrews 9:22 affirms that 'without the shedding of blood, there is no remission of sin.' This principle is established early in Scripture, as demonstrated by God clothing Adam and Eve with coats of skins, which required the death of an animal. This act foreshadows Christ's sacrificial death, where He shed His blood to atone for the sins of His people. The blood represents a substitutionary sacrifice, meeting the righteous requirements of God and allowing sinners to be reconciled to Him. The concept of substitution runs throughout Scripture, culminating in Christ's ultimate sacrifice on the cross.
