In Romans 7:14-25, Paul is not confessing that he continually practiced sin in his daily life, but that the threat of practicing it was always with him. He always had to be on guard against it to keep it from breaking out. And, at times, it did indeed break out, reminding him not only of its presence, but also its strength. There is no doubt Paul was a mature Christian. Therefore, Paul’s example serves as a reminder to us that, no matter how spiritually mature we become, human nature will still always be with us.
Thus, because we are similar to Paul, and despite the wretchedness we may feel, we have assurance, knowing we will be delivered from this peculiar situation, one that is somewhat akin to having a dual personality. Our deliverance is through Jesus Christ; there indeed is an end. However, unlike many Protestant groups that proclaim that we do not have to keep the law because all is done for us, we know that we must strive to walk even as Christ walked—and He never sinned.
