God raised Christ from the dead and seated him at his right hand in the heavenly places, far above all rule and authority and power and dominion, and every name that is named, not only in this world but also in the one to come. And he put all things under his feet.  Ephesians 1:21-22

Jesus defeated Satan on the cross legally, but we must actualize what Jesus legalized through His death.  He, like Joshua, is saying, “You must put your feet on the necks of my enemies even though I’ve already won the victory.”   God did His part, we must do our part.  If something is needed to complete it, God will finish it.  

That’s why the children of Israel were told to march around the wall seven times.  They obeyed, and then God activated the miracle by bringing the walls down.   He could have done it all without their involvement but He didn’t design mankind to be passive.  From the creation of Adam, the mission was clear.  Rule and subdue the earth. 

Consider a policeman who directs traffic.  He holds up his hand – cars stop.  He blows a whistle and points to the right – cars turn to the right.  Is he physically strong enough to move a car where it should go?  No, but he wears the badge that represents the authority he serves.  Perhaps that is why we instinctively take our foot off the gas and slightly brake at the sight of a police car.  We react to the authority of the one in the car before we ever see the person. 

We are powerless without the God of Israel behind us.  We are no match for an invisible enemy with an army behind him.  We would be defenseless, but instead, we are defended.  We would hide, but instead, we are equipped to expose.  We would retreat, but instead, we are told to advance.  We would be small and easily overtaken, but we are mighty and invincible because the Almighty stands behind us.   He has our back, but only as we use authority as it was intended ~ subject to the will of God.  It is never to be self-serving.

Adrian Rogers said this: Kingdom Authority is the God-given mandate of Christians to exercise control over the world in the name of Jesus and under His oversight.
