2 Corinthians 10:4-6

The weapons of our warfare are not physical [weapons of flesh and blood]. Our weapons are divinely powerful for the destruction of fortresses. We are destroying sophisticated arguments and every exalted and proud thing that sets itself up against the [true] knowledge of God, and we are taking every thought and purpose captive to the obedience of Christ, being ready to punish every act of disobedience, when your own obedience [as a church] is complete.
