How do we know the doctrine of Christ's kingship is true?

The doctrine of Christ's kingship is grounded in the fulfillment of prophecy and the witness of the New Testament. For instance, the wise men came to Jerusalem asking, 'Where is he that is born King of the Jews?' This indicates that His kingship was anticipated and recognized even at His birth. Multiple prophecies, such as those found in Micah 5:2 and Isaiah 9:6-7, affirm His royal status and sovereignty. Furthermore, the life of Jesus as depicted in the Gospels demonstrates His authority and the fulfillment of God's redemptive plan, further substantiating His role as King.
