Why is Christ’s priesthood important for salvation?

Christ’s priesthood is crucial because it establishes Him as the mediator par excellence who provides true and lasting access to God. In contrast to the Old Testament priesthood, which was temporary and needed continual sacrifices, Christ's priesthood represents a once-for-all sacrifice that fully satisfies divine justice. Hebrews 10:12 highlights this, stating, 'But this man, after he had offered one sacrifice for sins forever, sat down on the right hand of God.' Through His perfect sacrifice, sin is not just covered but entirely removed for believers, providing them with eternal life and peace with God. This truth underscores the centrality of Christ in salvation, making Him the only way to the Father (John 14:6).
