How does the blood of Christ make us holy?

The holiness that comes from the blood of Christ is foundational in Reformed theology, emphasizing that it is not through human efforts that we attain holiness but through Christ's atoning sacrifice. Hebrews 13:12 teaches that Jesus suffered outside the gate to sanctify the people through His own blood. This means that because of Christ's obedience and sacrifice, believers are given a new status as holy before God. It underscores the truth that the believer's standing in grace is not based on their works but on the sufficient and effectual work of Christ on the cross.
