Capture...to gain control over or exert influence over
Yes, as the Message says so beautifully, the world is unprincipled, its dog-eat-dog and the world does not fight fair. But we don't live or fight our battles that way. We use our powerful God given tools to tear down barriers against the truth of God and demolish corrupt culture, smash warped philosophies, and tear down barriers against His word. Take CAPTIVE every loose thought , emotion and impulse and align it with His word.
I am a great believer in recognizing and taking CAPTIVE the thoughts that would seek to destroy who we are in Him.
