2 Corinthians 10:1-5 NIV
By the humility and gentleness of Christ, I appeal to you—I, Paul, who am “timid” when face to face with you, but “bold” toward you when away! I beg you that when I come I may not have to be as bold as I expect to be toward some people who think that we live by the standards of this world. For though we live in the world, we do not wage war as the world does. The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. 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.
