ISB ~ Romans 7 v5

living in the flesh:i.e., living by the impulses of our fallen nature. Paul often speaks of “the flesh”, not as the body per se, but as the whole range of weaknesses we inherited from Adam, including (1) our corruptible bodies (8:3); (2) our darkened minds (1:21); (3) our inability to obey God without grace (8:7); and (4) our inclinations toward sin (7:25). The desires of the flesh are directly opposed to the will of the Spirit. See note on Gal 5:16-24.

our members:Our bodies can be used as instruments either of wickedness or of righteousness (6:13) (CCC 1995).
