For I know that in me (that is, in my flesh,) dwells no good thing: for to will is present with me; but how to perform that which is good I find not.
All Commentaries on Romans 7:18 Go To Romans 7
Augustine of Hippo
AD 430
It is possible for a good to be performed when there is no yielding to evil lust, but the good is completed or perfected only when evil lust itself no longer exists.
