Man’s Consciousness
While mankind has an inborn sense of right and wrong, the way in which each person or society applies this moral law varies. Man becomes a law unto himself.
14 (Indeed, when Gentiles, who do not have the [written Jewish] law, do by nature things required by the law, they are a law for themselves, even though they do not have the law. 15 They show that the requirements of the law are written on their hearts, their consciences also bearing witness, and their thoughts sometimes accusing them and at other times even defending them.) Rom. 2:14-15, NIV
