How do we know Christ's priesthood is important?

The priesthood of Christ, as highlighted in Hebrews 7, is essential for understanding our salvation. Unlike the Levitical priests, whose priesthood was temporary and based on lineage, Christ is a priest forever after the order of Melchizedek. This distinction means He provides a perfect and complete sacrifice for sins, having offered Himself once for all, as outlined in Hebrews 10:12. His ongoing intercession for believers assures us that we have access to God through Him, emphasizing the permanence and sufficiency of His priestly role.
