2 Corinthians 10:1-4

Now I, Paul, urge you by the gentleness and graciousness of Christ—I who am meek [so they say] when with you face to face, but bold [outspoken and fearless] toward you when absent! 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.
