Why is the blood of Christ significant for atonement?

In Leviticus 17:11, it is proclaimed that the life of the flesh is in the blood, which is given to make atonement for souls. This establishes the foundation for understanding Christ's blood in the New Covenant context; His sacrifice is a blood sacrifice that covers our sins and provides reconciliation with God. The significance of Christ's blood is vividly portrayed in the Passover narrative where the Israelites were saved through the blood of the lamb, illustrating that it is 'when I see the blood' that judgment passes over, a foreshadowing of the efficacy of Christ's blood in saving His people from the wrath of God.
