How do we know Jesus Christ is our perfect king?

In Psalm 101, David expresses aspirations for a reign marked by integrity and righteousness, traits that ultimately describe Jesus Christ, the perfect king. Unlike David, who sinned, Jesus never sinned in thought, word, or deed. His life was characterized by walking in a perfect way, and He fulfilled all righteousness for His people, serving as our representative before God. His kingship is predicated on His purity and ability to dispense grace while maintaining justice, making Him the only true king we can fully trust.
