How do we know that Christ's redemption is complete?

The completeness of Christ's redemption is affirmed in Hebrews 9:12, which states that He entered the holy place and obtained eternal redemption for us through His own blood. This signifies that the sacrifice was perfect and sufficient, as it required no additional payments or layaway; it was paid in full. The connection between Christ's sacrifice and the believer's redemption is foundational in Reformed theology, underscoring that there is nothing more needed for salvation than faith in His completed work.
