This is not a call for only the 1st century and it is not an empty call for any other century. If Christ has called us to do this, “make disciples of all nations,” He has called us to do what is possible. It may be a long and arduous road but it is one that is to be traveled by His power and for His glory. We are to seek to disciple the nations and teach them to “obey” and that obedience is accomplished by a work of God, but it can be accomplished by His people seeking to obey Him in making disciples.
Matt 6:9-13 "Our Father in heaven, hallowed be your name. Your kingdom come, your will be done, on earth as it is in heaven. Give us this day our daily bread, and forgive us our debts, as we also have forgiven our debtors. And lead us not into temptation, but deliver us from evil"
This passage is speaking not simply of some future event, "this day", to pray for but what the disciples were to pray for and seek after then as we are to pray and seek after now. We are to pray for His kingdom to be manifested in and though His people which is then exhibited in their works as James makes abundantly clear. The result of God’s people living out His word, all of it, in the world by His power is a changed world. The first century Christians changed the world by their lives can we and should we not do the same. Dominion starts with God having dominion over his people and then moves out from there.
2 Cor 5:17 “Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come.”
Of course this change starts by God's power in the hearts and minds of His people by God's writing of His law on their hearts (Jer 31:31ff). This is a changed heart is one that radically transforms God’s elect. 2 Cor 5:17 is not a simply a wish but a reality accomplished by the hand of God and is where dominion begins. This change does not end with the individual but is to extend to all of God’s creation as He uses His people as the means to bring all things under His rule. We are to realize that the dominion and the change that God desires is wrought by Him by the means of the Spirit and the work of His people for His glory.
Dominion is not a word to fear but one to embrace as the call of His children.
