How do we know that Christ is King in His kingdom?

The affirmation of Christ's kingship is grounded in His authority as the Son of God, which is demonstrated through His life, death, and resurrection. In Matthew 13, Jesus indicates that He is the sower of good seed, symbolizing the advancement of His kingdom. Additionally, scriptures like Psalm 2 assert that God has set His King upon His holy hill, illustrating that Christ reigns globally, over all creation. This sovereignty is not dependent on earthly recognition; rather, it is evidenced in the lives of believers who willingly submit to His governance and the transformation it brings in their hearts.
