2 Corinthians 10:3-6 New International Version (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.
