David ruled the earth by the pronouncements of the axioms. The work of the Spirit through the prophetic word.  
Acts 13 22. After removing Saul, he made David their king. He testified concerning him: 'I have found David son of Jesse a man after my own heart; he will do everything I want him to do.'

. Christ took control over all things when He ascended to heaven. The work of the Spirit through the prophetic word.   Kiss the Son lest He be angry and you be destroyed in your way.
33he has fulfilled for us, their children, by raising up Jesus. As it is written in the second Psalm: " 'You are my Son;today I have become your Father. 34The fact that God raised him from the dead, never to decay, is stated in these words:" 'I will give you the holy and sure blessings promised to David.' 35So it is stated elsewhere:" 'You will not let your Holy One see decay.'

The holy blessing are the axioms on steroids and extended to the ends of the earth.
38 "Therefore, my brothers, I want you to know that through Jesus the forgiveness of sins is proclaimed to you. Through him everyone who believes is justified from everything you could not be justified from by the law of Moses. Take care that what the prophets have said does not happen to you
Paul establishes the creation covenant. Every man is his own governor because he is held accountable to the law of government.  God sets up through His law. God works from the top down. All men govern themselves since there is not occupation that escapes Gods equal judgements. "the rogue nations devour my people as men eat bread." Man is able to rule the earth through governing law.  
 Rom 3 "There is no one righteous, not even one;
       here is no one who understands,
       no one who seeks God.
   All have turned away,
       they have together become worthless;
   there is no one who does good,
       not even one."
   "Their throats are open graves;
       their tongues practice deceit."
   "The poison of vipers is on their lips."
       "Their mouths are full of cursing and bitterness."
   Their feet are swift to shed blood;
       ruin and misery mark their ways,
   and the way of peace they do not know."
       There is no fear of God before their eyes."
God has provided the eternal pronouncements in order for His elect can rule the earth. We can overcome all opposition because He has sworn against His own hurt that He will fulfill the prophet pronouncements. 
  Rom 8Who will bring any charge against those whom God has chosen? It is God who justifies. Who is he that condemns? Christ Jesus, who died--more than that, who was raised to life--is at the right hand of God and is also interceding for us. Who shall separate us from the love of Christ? Shall trouble or hardship or persecution or famine or nakedness or danger or sword? As it is written:
   "For your sake we face death all day long;
       we are considered as sheep to be slaughtered No, in all these things we are more than conquerors through him who loved us. For I am convinced that neither death nor life, neither angels nor demons,neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.
