{Under the law} (hupo nomon). Instead of "under the flesh"
as one might expect. See  Ga 3:2-6  for contrast between law and
spirit. The flesh made the law weak ( Rom 8:3  Heb 9:10,13 ).
They are one and the same in result. See same idea in  Ro 8:14 .
Note present tense of agesthe (if you are continually led by
the Spirit). See verse  23 .
