2 Corinthians 10:3-6

For though we walk in the flesh, we do not war after the flesh: (for 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; and having in a readiness to revenge all disobedience, when your obedience is fulfilled.
