For though we walk in the flesh, we do not war according to the flesh:
All Commentaries on 2 Corinthians 10:3 Go To 2 Corinthians 10
John Chrysostom
AD 407
Here he goes on to alarm them also by the figure he uses, 'for,' says he, 'we are indeed encompassed with flesh; I own it, but we do not live by the flesh;' or rather, he said not even this, but for the present reserves it, for it belongs to the encomium on his life: but first discourses of the Preaching, and shows that it is not of man, nor needs aid from beneath. Wherefore he said not, 'we do not live according to the flesh,' but, we do not war according to the flesh, that is, 'we have undertaken a war and a combat; but we do not war with carnal weapons, nor by help of any human succors.'
