Why is understanding the priesthood of Jesus important for Christians?

The recognition of Jesus as our eternally functioning High Priest is essential for Christians as it emphasizes the complete and definitive nature of His sacrifice and intercession. Unlike the Levitical priests who were limited by mortality and sin, Jesus, through His death and resurrection, has secured an unchangeable priesthood. Hebrews 7:24-25 states that He is able to save to the uttermost those who come to God through Him, because He lives to make intercession. This assures believers that their salvation is not dependent on a series of mortal priests but is rooted in the eternal work of Christ, which provides both security and assurance of God's grace.
