“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;)”
King James Version (KJV)
2:15 Who show - To themselves, to other men, and, in a sense, to God himself. The work of the law - The substance, though not the letter, of it. Written on their hearts - By the same hand which wrote the commandments on the tables of stone. Their conscience - There is none of all its faculties which the soul has less in its power than this. Bearing witness - In a trial there are the plaintiff, the defendant, and the witnesses. Conscience and sin itself are witnesses against the heathens. Their thoughts sometimes excuse, sometimes condemn, them. Among themselves - Alternately, like plaintiff and defendant. Accusing or even defending them - The very manner of speaking shows that they have far more room to accuse than to defend.
Ro 2:15 Which shew. Such Gentiles, not having the law, are a law to themselves, for they show forth in their lives that the essential principles of the law are written in their hearts. Not only do their outward acts testify, but their conscience, which condemn or approve their own acts, or those of others. That is, their consciences testify as to distinctions between right and wrong. They have a moral sense.
