Romans 2:15 - Clarke's commentary and critical notes on the Bible

Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another;) Which show the work of the law - In acting according to justice, mercy, temperance, and truth, they show that the great object of the law, which was to bring men from injustice, cruelty, intemperance, and falsity, is accomplished so far in them: their conscience also bearing witness - that faculty of the soul, where that Divine light dwells and works, shows them that they are right; and thus they have a comfortable testimony in their own souls of their own integrity: their thoughts, the mean while, accusing, or else excusing one another; or rather, their reasonings between one another accusing or answering for themselves. As if the apostle had said: - And this point, that they have a law and act according to it, is farther proved from their conduct in civil affairs; and from that correct sense which they have of natural justice in their debates, either in their courts of law, or in their treatises on morality. All these are ample proofs that God has not left them without light; and that, seeing they have such correct notions of right and wrong, they are accountable to God for their conduct in reference to these notions and principles. These seems to be the true meaning of this difficult clause. See below.
