Why is Christ's sacrifice essential for our perfection?

The necessity of Christ's sacrifice for our perfection is central in Reformed theology. As highlighted in the sermon, the law cannot make us perfect, and our attempts to achieve righteousness through works lead only to condemnation (Hebrews 7:19). Christ's perfect sacrifice is the only means through which our sins are atoned, as He fulfills the demands of the law on our behalf. The blood of Christ creates the everlasting covenant spoken of in Hebrews 13:20, ensuring that anyone who trusts in Him is justified and seen as perfect before God. This truth anchors our confidence; without His sacrifice, we would remain in our sins with no hope of perfection.
