The Purpose of the Sword

"For though we walk in the flesh, we do not war according to the flesh, for the weapons of our warfare are not of the flesh, but divinely powerful for the destruction of fortresses. [We are] destroying speculations and every lofty thing raised up against the knowledge of God, and [we are] taking every thought captive to the obedience of Christ." (2 Corinthians 10:3-5)
