2 Corinthians 10:3-6

For although we do live in the world, we do not wage war in a worldly way; because the weapons we use to wage war are not worldly. On the contrary, they have God’s power for demolishing strongholds. We demolish arguments and every arrogance that raises itself up against the knowledge of God; we take every thought captive and make it obey the Messiah. And when you have become completely obedient, then we will be ready to punish every act of disobedience.   — 2 Corinthians 10:3-6
