2 Corinthians 10:3-6

It is true that we live in the world, but we do not fight from worldly motives. The weapons we use in our fight are not the world's weapons but God's powerful weapons, which we use to destroy strongholds. We destroy false arguments; we pull down every proud obstacle that is raised against the knowledge of God; we take every thought captive and make it obey Christ. And after you have proved your complete loyalty, we will be ready to punish any act of disloyalty.
