How does Christ's priesthood relate to the new covenant?

The new covenant, established through Christ's blood, signifies a transformative change from the old covenant characterized by the Mosaic law. Christ's role as a mediator of this new covenant showcases His superior priesthood, which not only provides forgiveness of sins but also empowers believers to live in accordance with God's will. The promises within this new covenant are better because they are rooted in the work of Christ, ensuring that believers experience a true relationship with God rather than a mere adherence to law.
