Jesus is the power of God. It is HIS obedience that pulls down strongholds. We are chasing our own tails if we think we can conquer our flesh with our own fleshly efforts. It is life and power that we need and that only comes through what has already been purchased for us in Jesus.
I thought taking thoughts captive meant I was always to be policeman to my own mind, but I am coming to believe that is not what is meant at all! We have the mind of Christ, but not because we produce it in ourselves, we have it only because it is available to us so that we can rely on it for what we need. It is not by our obedience that we bring thoughts into captivity, it is by HIS! It is basically, bring them (thoughts) into captivity to what has already been accomplished. Bring them captive to grace. To the “obedience of Christ.” To the gift of righteousness and all things freely given in Him. For it is by this, “by one man’s obedience that the many will be made righteous.”
