What does the Bible say about Jesus as our King-Priest?

The Bible reveals Jesus Christ as both King and Priest, fulfilling the roles no one else could. In Psalm 110, it’s declared that He is a priest forever after the order of Melchizedek, emphasizing His unique position. Unlike the Old Testament priests who never sat down because their work was never complete, Jesus' sacrificial work is finished, as He proclaimed in John 17. His resurrection and exaltation at the right hand of God affirm His dual office as King-Priest, ruling over all creation.
