Romans 7:15

Verse 15. For that which I work, I understand not. To know, or understand is often, in the style of the Scriptures, the same as to approve or love: so the sense here is: I approve not what I do, that is, what happens to me in my sensitive part, in my imagination, or in the members of my body, which indeed the just man rather suffers than does; and this is the sense, by what immediately follows, the evil which I hate, that I do, that is that I suffer, being against my will; and I do that which I would not. Witham.—I do not that good which I will, and so forth The apostle here describes the disorderly motions of passion and concupiscence; which oftentimes in us get the start of reason, and by means of which even good men suffer in the inferior appetite what their will abhors: and are much hindered in the accomplishment of the desires of their spirit and mind. But these evil motions, (though they are called the law of sin, because they come from original sin, and violently tempt and incline to sin) as long as the will does not consent to them, are not sins, because they are not voluntary.
