2 Corinthians 10:3 - 5
10:3 
      For though we walk in the flesh, we do not war after the flesh: 
 10:4 
      (For the weapons of our warfare are not carnal, but mighty through God to the pulling down
      of strong holds;) 
 10:5 
      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; 
 10:6 
      And having in a readiness to revenge all disobedience, when your obedience is fulfilled.
