He [Christ] disarmed the rulers and authorities [and] made a public display of them, having triumphed over them through Him (Colossians 2:15).
In Colossians 2:15, 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 de-clawed, 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. In Ephesians Paul wrote that his call was "to bring to light what is the administration of the mystery which for ages has been hidden in God, who created all things; in order that the manifold wisdom of God might now be made known through the church to the rulers and authorities in the heavenly places. This was in accordance with the eternal purpose which He carries about in Christ Jesus our Lord" (Ephesians 3:9-11).
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."
In Your name, Lord, I will take an active stand against the devil and his demons, renouncing both apathy and fear.
