What role does Christ's blood play in repentance?

In the context of repentance, the blood of Christ represents the sacrificial atonement necessary for the forgiveness of sins. Hebrews 9:22 affirms that without the shedding of blood, there is no remission of sins. True repentance understands that no human efforts can atone for sin; it is solely through Christ's sacrifice that a believer can be made clean. This recognition leads to a change of mind and heart, where one turns away from sin and toward God, resting on the assurance that Christ’s blood effectively covers all transgressions.
