How do we know Jesus is our spiritual king?

Jesus Christ fulfills Old Testament prophecies detailing the arrival of a king, as seen in Zechariah 9:9. He comes not in military might but in humility, riding on a donkey — indicative of His purpose of peace. His role as spiritual king is further validated through His teachings and atoning work. Jesus’ mission was not about earthly power but rather about delivering His people from the bondage of sin. By laying down His life and rising again, He establishes His authority and invites believers into His kingdom.
