7:18 no good thing. Paul, before his conversion, could boast that he was, as “touching the righteousness which is in the law, blameless” (Philippians 3:6). But then he came to see that all his “righteousnesses [were] as filthy rags” (Isaiah 64:6), and accepted “eternal life through Jesus Christ” (Romans 6:23). If such a man as Paul would have to confess that in his flesh there was nothing good at all, then surely every Christian must say the same.
