Why is it important to understand Jesus as both apostle and high priest?

In Hebrews 3:1, Jesus is referred to as both the apostle and high priest of our profession. This dual role signifies that He is not only the messenger bringing the gospel to us but also the one who fulfills the requirements of the Law through His sacrificial death. As the apostle, He reveals God’s plan for redemption. As the high priest, He intercedes for us and offers Himself as the ultimate atonement for our sins. This highlights the completeness of Christ's work on our behalf, ensuring our reconciliation with God.
