Why is iniquity pardoned through Christ's blood?

The concept of iniquity being pardoned through Christ's blood is foundational in Reformed theology. Hebrews 9:22 teaches that without the shedding of blood, there is no remission of sin. This underscores the necessity of Christ's sacrificial death as the means of atonement. His blood serves not only as a covering but as a cleansing agent that removes the guilt of sin and restores fellowship with God. This reconciliation is made available to all who come to Christ in faith, affirming the belief that salvation is wholly of grace and rests upon the sufficiency of Christ’s sacrifice.
