What does it mean that Jesus is King?

Jesus’ kingship is a fundamental aspect of His identity and mission, underscored in passages like Mark 15:26, where the inscription above His cross identifies Him as 'Jesus of Nazareth, the King of the Jews.' This title, though intended to mock, reflects a profound truth about His authority and role in God’s redemptive plan. His kingship is not one of earthly power but rather a spiritual reign that encompasses all creation. In Revelation 19:16, He is called 'King of Kings and Lord of Lords,' affirming His ultimate sovereignty. Christ's kingdom is established through His sacrificial work on the cross, which brings salvation to those who believe, demonstrating that His reign is rooted in grace and truth, inviting all to submit to His authority and enjoy the blessings of His kingdom.
