Why is the priesthood of Christ essential for Christians?

The significance of Christ's priesthood lies in the fact that He acts as the sole mediator between God and man. According to Hebrews 10:12, Christ offered one sacrifice for sins that is eternal and once for all, emphasizing that no further sacrifices are needed. His priesthood guarantees that He is capable of interceding for our behalf before the Father, ensuring that we are accepted in light of His completed work. This understanding empowers believers with confidence in their salvation, as we can approach God freely knowing that Christ's sacrifice has removed the barrier our sin has created. Thus, His priesthood not only provides salvation but also maintains our ongoing relationship with God.
