2 Corinthians 1:12

12 For our proud confidence is this: the testimony of our conscience, that in holiness and godly sincerity, not in fleshly wisdom but in the grace of God, we have conducted ourselves in the world, and especially toward you.

2 Corinthians 10:4

4 for the weapons of our warfare are not of the flesh, but divinely powerful for the destruction of fortresses.
