You are cruising down the highway in a 22 wheeler truck doing about 100 km per hour. You can feel the power of the truck as it rolls down the road when you notice a tiny figure about 400 meters away stepping into the middle of the road. As you get closer you realize it’s a policeman and he is motioning for you to pull over. Immediately you step on to the breaks and you bring this powerful machine to halt simply because a tiny man stepped onto the road and motioned you to stop. Why, because the police man has authority. Authority is delegated power, and should you choose to ignore the policeman and run him over then the full wrath of the government will be upon you because that is the institution that has delegated the authority to the policeman
18 Jesus came up and said to them, “All authority (all power of absolute rule) in heaven and on earth has been given to Me. .
Think about this, if ALL authority that is all power of absolute rule in heaven and on earth was given to Jesus, then what power and authority does the devil have?
Luke 10:19 (AMP)
19 Listen carefully: I have given you authority [that you now possess] to tread on [a]serpents and scorpions, and [the ability to exercise authority] over all the power of the enemy (Satan); and nothing will [in any way] harm you.
All authority in heaven and on earth was given to Jesus and He in turn gave it to us. The only power that the enemy will have over us is the power we give him.
Many Christians don’t understand the power and authority we have been commissioned to walk in as believers. We walk around scared of the devil looking for someone to pray for us because we have been so intimidated by the devil. Truth is that we have authority over ALL the power of the enemy.
Authority comes to effect only when it is exercised. Just because you have authority does not mean a thing until you exercise it. The policeman can stay on the side of the road scared of all this big trucks that can run him down if he steps on to the middle of the road. He can stay there depressed waiting for someone to help him cross and as long as he does nothing then the powerful trucks will zoom past him. It is only when he chooses to exercise his authority and in faith step onto the middle of the seemingly dangerous road and he holds up his hand then he realizes that the truck drivers are subject to him.
