The opposite of obedience is disobedience, and God has a lot to say about that, too. Our first line of defense against disobedience is to "take every thought captive to obey Christ." We are not in a physical battle, but a daily spiritual battle. Testing our thoughts against the Word of God helps us determine if we're being attacked and drawn into disobedience. If we stop thoughts that don't line up with Scripture right in their tracks, we're kept from harming ourselves or others with words or actions.
