I don’t think Paul is saying that he doesn’t offer his members unto righteousness or that he doesn’t make efforts to resist sin and obey God’s law. Could it be it’s just that he (we) never graduated from needing the sufficiency of Christ’s atonement in order that his every thought, word, and deed be cleansed and made acceptable to God? For none of Paul’s good works could attain to the perfection of the Law anymore than ours can, that perfection of the Father in heaven to which he and we are called. He lacked the inherent holiness or “ability to carry it out.” So, in our walk of obedience to God as we daily offer ourselves up as servants for righteousness (Rom. 6: 13), and in order that our consciences may be comforted, we must always keep our eyes not only on the law of Christ to guide our obedience but on the good news that “There is therefore now no condemnation for those who are in Christ Jesus.” (Romans 8:1 ESV)
