When you hear the glad news that Christ is King, the thing to do is to submit to His rule. When you repent for your sins and believe in Jesus Christ, God establishes His rule in your heart. This is part of what Jesus meant when He said, “the kingdom of God is within you” (Luke 17:21). Anyone who has ever entered that kingdom has done so by praying to God, “Your kingdom come” or words to that effect. That is the way the kingdom comes to you and the way you come into the kingdom. To become a Christian is simply to ask God to set up His throne as the supreme King of your heart.
