But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you. (Matthew 6:33 KJV)
The kingdom of God is the domain where the rule of Christ is voluntarily accepted by those who acknowledge His claim of authority in Heaven and on Earth (Matthew 28:18). It is an authority which seeks to establish itself through invitation rather than domination. It is the way of the world to dominate people and make them submit, but the way of Christ is humility and servant hood (Mark 10:42-45). Christ did not establish His rule on earth by domination but by self-sacrifice, in love and humility, inviting people to follow Him and voluntarily submit to His Lordship. Those who accept His authority are also called to go into all the world and to invite people to become His disciples. It is an invitation to people to voluntarily submit to Christ’s authority which means learning to obey all He commanded us (Matthew 28:19). Those who humbly submit to Him receive the righteousness of Christ. Not only does it mean that they are made right with God, but they also receive the Holy Spirit in their hearts who writes His law of Love in their inner being so that they also learn to live right in accordance with Christ’s Law of Love. In this manner Christ is with them all the days of their lives, as Lord, establishing His gentle dominion of love (Matthew 28:20).
