How do we know Jesus Christ is the King of kings?

The title 'King of kings' applied to Jesus signifies His supremacy over all earthly rulers. He is described in Scripture as the one who executes authority not only in heaven but also on earth. In 1 Timothy 6:15, it's emphasized that He is the only potentate, which includes being the King of kings, indicating that He operates independently and effectively without requiring human approval or governance. His reign is validated by His fulfillment of prophetic scriptures and His omnipotent presence in all aspects of existence.
