2 Corinthians 10:2-5

I ask that when I do come I will not be driven to the boldness that I intend to show toward those few who regard us as if we walked according to the flesh [like men without the Spirit]. For though we walk in the flesh [as mortal men], we are not carrying on our [spiritual] warfare according to the flesh and using the weapons of man. The weapons of our warfare are not physical [weapons of flesh and blood]. Our weapons are divinely powerful for the destruction of fortresses. We are destroying sophisticated arguments and every exalted and proud thing that sets itself up against the [true] knowledge of God, and we are taking every thought and purpose captive to the obedience of Christ
