Why is Christ being our high priest significant for believers?

The significance of Christ as our high priest for believers cannot be overstated. He mediates between God and humanity, fulfilling what the Old Testament priesthood foreshadowed. In Hebrews 4:14-16, we are encouraged to approach the throne of grace with confidence because of Christ's understanding of our struggles; He was tempted as we are but without sin. This means that believers have direct access to God through Christ, and He continually intercedes on our behalf. Thus, our relationship with God is secured by the perfect righteousness of our high priest, instilling assurance and comfort.
