Colossians 2:15 And having disarmed the powers and authorities, he made a public spectacle of them, triumphing over them by the cross.
Paul identifies something very important that happened at the death, resurrection and ascension of Christ. Not only were we made alive in Christ, but Satan was also disarmed and defeated. His defeat is not pending, nor is it future; it has already happened.
If Satan is already disarmed, why don’t we experience more victory in our lives? In a word, the lie. Satan roams around like a hungry lion, looking and sounding ferocious. In reality his fangs have been removed and he has been declawed, but if he can deceive you into believing that he can chew you up and spit you out, he can control you, which is just what he wants to do. He is gumming Christians to death!
The very reason Christ conferred His authority on us was to demonstrate to the kingdom of darkness who is really in control in this world. Ephesians 3:9and to make plain to everyone the administration of this mystery, which for ages past was kept hidden in God, who created all things. 10His intent was that now, through the church, the manifold wisdom of God should be made known to the rulers and authorities in the heavenly realms, 11according to his eternal purpose that he accomplished in Christ Jesus our Lord
How are we doing at making Christ’s victory known to “the rulers and authorities in heavenly places,” which is God’s eternal purpose? In many quarters, not very well. Some of us are still saying, “What rulers and authorities?” We’re not sure that demons even exist. How are we ever going to get our job done in the world if we don’t believe what God says about the kingdom of darkness? Others of us are cowering in the corner pleading, “O God, please help us! The devil is roaring at us!” And God responds, “I’ve done all I’m going to do. I defeated and disarmed Satan at the cross. I conferred all authority on you in Christ. Now open your eyes. Realize who you are and start demonstrating the authority you already possess.”
