Why is the high priest role of Jesus important?

The role of Jesus as our high priest is of utmost importance in the Reformed understanding of salvation. Hebrews 7:24-27 clarifies that 'this man, because he continueth ever, hath an unchangeable priesthood,' allowing Him to save those who come to God through Him. Unlike the Old Testament priests who offered daily sacrifices, Jesus offered Himself once for all, fulfilling the law and providing a perfect and eternal redemption for His people. This priestly role means that He does not merely mediate on our behalf; He is the effective sacrifice for our sins, ensuring that we are justified before God. His continuing intercession as our high priest provides believers with the assurance that we are always represented before the Father, allowing us to confidently approach Him.
