It can take a while to recognize the adversary because he comes disguised as my very own thoughts. Grim thoughts take me down a dark road into a forest of negative feelings and emotions. I don’t have to follow where they want to lead. Rebel thoughts and emotions are subdued by the life of Christ as I discern His impulses within me. He prompts the quick release of a negative thought and through union awareness I yield the natural corresponding impetus to let it go. I cast down imaginations, recognizing them for the poison they are. Erroneous, lie infested thoughts will lead me to the emotions they want me to feel. If I entertain the thoughts and find myself caught up in ugly feelings then I will soon find myself behaving falsely. Feelings empower behavior. With the practice of bringing thoughts into captivity they are soon denied the freedom they once had in me. I break the intimacy I formerly had with old thought patterns. Going silent means detaching from the company of erstwhile thoughts. As imaginations are cast down, thoughts come into the obedience (under the authority) of Christ.
The weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds; casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ. 2 Corinthians 10:4-5 (KJV)
The arms with which we are fighting are not those of the flesh, but they are strong before God for the destruction of high places; putting an end to reasonings, and every high thing which is lifted up against the knowledge of God, and causing every thought to come under the authority of Christ. 2 Corinthians 10:4-5 (BBE)
