2 Corinthians 10:3-6 (NIV)
3 For though we live in the world, we do not wage war as the world does. 4 The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. 5 We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ. 6 And we will be ready to punish every act of disobedience, once your obedience is complete.
