Romans 7:20 : But if what I would not, that I do, it is no more I that do it, but sin that dwelleth in me. This verse is almost a repetition of Rom 7:17. Even when the alien sinner would do good, he finds that sin hinders him. Paul is picturing the helplessness of the sinner without Christ--without the regenerating and saving power of the gospel. Here again is emphasized the need of the power of the gospel. The inward man, the spirit, in its contest with the passions of the flesh is helpless without the gospel.
