In the kingdom of power, the Triune God rules without means according to His omnipotence and omnipresence. God has always been and will always be the King of heaven and earth. At the incarnation of the Son of God, the human nature of Christ was given authority in heaven and on earth. Although all things have been put in subjection to Him, not all things are subject to Him. “For He must reign till He has put all enemies under His feet” (1 Cor 15:25).
This class examined the two kingdoms: this world(the state) and grace (the church). In the kingdom of this world, God rules the subjects of this kingdom, both believers and unbelievers, by means of law and the governing authorities. Human reason is the guide for governance in this world. In the kingdom of grace, God rule the subjects of this kingdom, only believers, by means of the Word (both the law and the promise of the Gospel) and sacraments and the apostolic/pastoral office. Although these two kingdoms are distinct they are not mutually exclusive. The church is IN the world, but not OF the world (John 17:11-15).
