Verse 14 But I am carnal; that is, man is carnal. The idea seems to be that the law itself is holy; it is the man who is to be charged with the sin which the exhibition of the law develops. The pronoun I continues to be used through the remainder of the chapter, as representing human nature; though some suppose that renewed, and others that unrenewed, human nature is denoted. The language is easily susceptible of an interpretation adapted to either supposition; but the latter seems most in accordance with the general design of the apostle in this discussion, which is, to show the utter inefficacy of the law to sanctify and save those who are under its dominion. We may, therefore, understand the Romans 7:15-25, to the close of the chapter, as representing the fruitless struggles and the difficulties which would be encountered in an attempt made by one possessing the sinful nature of man, to secure his salvation by the law.
