in that they show the work of the law written in their hearts, their conscience bearing witness therewith, and their thoughts one with another accusing or else excusing them);

Because the work of the law is seen in their hearts, their sense of right and wrong giving witness to it, while their minds are at one time judging them and at another giving them approval;

οιτινες δεικνυουσι το εργον του νομου γεγραμμενον εν ταις καρδιαις αυτων, εχοντες συμμαρτυρουσαν την συνειδησιν αυτων και τους λογισμους κατηγορουντας η και απολογουμενους μεταξυ αλληλων,

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;)
