How do we know that Jesus is truly King?

The truth of Jesus's kingship is deeply rooted in the prophetic Scriptures. For instance, Hebrews 5:5-10 describes Jesus as a high priest forever after the order of Melchizedek, signifying His unique role as both King and Priest. Furthermore, His authority is affirmed by His miraculous works and teachings during His earthly ministry, where He clearly declares His identity, as seen in John 18:37. Ultimately, His resurrection confirms His kingship, showcasing His victory over sin and death, establishing Him as the reigning King.
