How does the blood of Christ apply to believers?

The application of Christ's blood is essential for salvation. Just as the Israelites had to apply the blood of the Passover lamb to their doorposts (Exodus 12:7), believers must have the blood of Christ applied to their hearts through the work of the Holy Spirit (Hebrews 9:14). This signifies a personal acceptance of Christ's sacrifice and the transformative work of regeneration. The Holy Spirit applies this cleansing blood during the new birth, resulting in a believer's identity being wholly secured in Christ. Thus, it is not merely knowing about Christ's sacrifice but embracing it by faith that leads to salvation.
