How do we know Jesus is the King of the Jews?

Jesus' title as the King of the Jews is affirmed in the Gospels, particularly in Mark 15:26, where the inscription above the cross declares Him as such. This title emphasizes not only His Jewish heritage as a descendant of David but also His divine kingly authority. Throughout His life, Jesus demonstrated His kingship through His teachings, miracles, and interactions with people, showing that His kingdom is not of this world. Furthermore, the fulfillment of Old Testament prophecies regarding the Messiah supports His identity as King. In response to Pilate, Jesus affirmed His kingship, stating that His kingdom is not of this realm, thus illustrating that His rule is of a spiritual authority that transcends earthly power.
