How do we know that Christ is our sacrifice?

Christ fulfills the role of our sacrifice as indicated in the sacrificial system laid out in the Old Testament, including the requirements for the Nazarite. He embodies both judgment for our sin, as He atones for our transgressions, and provides meritorious honor to God through His perfect obedience and sacrifice. This dual function highlights that even our best efforts are insufficient, and they must be couched in faith, relying on Christ's work to satisfy God's requirements for holiness. Thus, believers are continually reminded that it is through Him that we are deemed acceptable rather than reliant on our own deeds.
