Why is the priesthood of Jesus Christ important for Christians?

Hebrews speaks of Jesus as our great high priest, after the order of Melchizedek, indicating that He supersedes the Levitical priesthood established in the Old Testament. Unlike the Levitical priests who had to offer daily sacrifices, Jesus offered Himself once for all, satisfying divine justice and securing our eternal redemption. His priesthood is rooted in His sinless nature and perfect obedience, providing believers with the assurance that our sins are forgiven and we have direct access to God. This makes His priesthood essential for Christians, as it assures us of His continuous intercession and advocacy before the Father.
