2 Corinthians 10:3-5
3 For though we walk in the flesh, we do not war after the flesh:
4(For the weapons of our warfare are not carnal, but mighty through God to the 
pulling down of strong holds;)
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.
