2 Corinthians 10:3

in the flesh To walk inthe flesh is to possess the fleshly nature with its many infirmities (see Romans 7). To walk afterthe flesh is to neglect the dictates of the higher spiritual nature, and to live as though the desires of the body were the only ones that needed satisfying.

war after the flesh The metaphor of a warfare, as applied to the Christian life, is a common one with St Paul, though it is more usually used of the internal conflict of the Christian soul than of the external warfare waged against the evil around. See 1 Corinthians 9:26; Ephesians 6:10-17; 1 Thessalonians 5:8; 1 Timothy 1:18; 1 Timothy 6:12; 2Ti 2:3-4; 2 Timothy 4:7. Bp Wordsworth remarks on the fact that "the armies of Imperial Rome, her camps and her campaigns," and the rest, were "objects that presented themselves to St Paul in his travels, and were very familiar to his readers." Cf. ch. 2 Corinthians 2:14-16.
