The greatest kingdom is the kingdom of God. The place where God desires to share all His goodness with His people. Those who are obedient to carry out His will and purposes are those who are already members of His Kingdom. They are repentant, forgiven, blood bought children filled with the Spirit of God. These people desire to follow the Lord and do what He has commanded for their lives, day by day. Already they are carrying out and fulfilling, in Christs name, the truth and goodness of the will of God. These people have already become citizens of the kingdom of God.
