Romans 7:8 - Matthew Poole's English Annotations on the Holy Bible

But sin; i.e. the corruption of our nature, the depraved bent and bias of the soul, called before lust. Taking occassion by the commandment; i.e. being stirred up or drawn forth by the prohibition of the law. The law did not properly give occasion, but sin took it. The law (as before) is not the cause of sin, though by accident it is the occasion of it. In a dropsy, it is not the drink that is to be blamed for increasing the disease, but the ill habit of body. Such is the depravedness of man's nature, that the things which are forbidden are the more desired: the more the law would dam up the torrent of sinful lusts, the higher do they swell. The law was given to restrain sin, but through our corruption it falls out contrarily. The law inhibiting sin, and not giving power to avoid it, our impetuous lusts take occasion or advantage from thence, the more eagerly to pursue it. Wrought in me all manner of concupiscence; i.e. inordinate affections and inclinations of all sorts. For without the law; i.e. without the knowledge of the law. Sin was dead; i.e. comparatively dead. Sin hath not so much power, either to terrify the conscience, or to stir up inordinate affections; it is like a sleepy lion, that stirs not.
