Why is Christ referred to as our High Priest?

In the context of Christian theology, Christ is referred to as the High Priest because He fulfills the role that the Levitical priests once performed, but in a far superior manner. The Levitical priests entered the earthly tabernacle to offer sacrifices repeatedly; however, their sacrifices could never completely atone for sin (Hebrews 9:6-7). In contrast, Christ entered the heavenly sanctuary once, offering His own blood as a perfect and final sacrifice, which not only atoned for sins but also provides eternal redemption (Hebrews 9:12). This role emphasizes His unique position as both the mediator between God and humanity and the ultimate sacrifice, which allows believers to draw near to God with confidence (Hebrews 10:22). His priesthood is after the order of Melchizedek, signifying an everlasting priesthood that guarantees His eternal intercession for His people.
