How do we know Christ is the King of Kings?

In Isaiah 33:17, the prophet alludes to a king whose beauty and grandeur reflect divine sovereignty, ultimately pointing us toward Jesus Christ, the King of Kings. This title signifies His unmatched authority and role as our Savior. Throughout Scripture, Christ's kingship is affirmed through various prophetic fulfillments and His sacrificial death and resurrection. As believers engage with their faith, they come to recognize and behold Him in His beauty, which is made known through His saving work and His current reign at the right hand of the Father.
