The good news of the Kingdom of God was the main message of Jesus’ ministry upon the earth. What is the message of the Kingdom, and why was it so important to Jesus? The Kingdom is God's government. The good news that Jesus preached was about the government of God being restored on earth after man had relinquished his dominion to Satan. Since the great sacrifice of Jesus on the cross, the Kingdom of God is being established on earth again. For those who accept God’s governmental authority, righteousness, peace, and joy are available once again. God reigns, and He chose to reveal His heavenly authority to us through earthly authorities whom He has established. To be submitted to God and His Kingdom involves being subject to His delegated authorities. It is essential for every Christian to identify his or her realm of authority.
