2 Corinthians 10:3-6 (NKJV)
For though we walk in the flesh, we do not war according to the flesh. 4 For the weapons of our warfare are not carnal but mighty in God for pulling down STRONGHOLDS, 5 casting down ARGUMENTS and every HIGH THING that exalts itself against the knowledge of God, bringing EVERY THOUGHT into captivity to the obedience of Christ, 6 and being ready to punish all disobedience when your obedience is fulfilled.
