14 When Gentiles, who do not have the Law [since it was given only to Jews], do instinctively the things the Law requires [guided only by their conscience], they are a law to themselves, though they do not have the Law. 15 They show that the essential requirements of the Law are written in their hearts; and their conscience [their sense of right and wrong, their moral choices] bearing witness and their thoughts alternately accusing or perhaps defending them 16 on that day when, as my gospel proclaims, God will judge the secrets [all the hidden thoughts and concealed sins] of men through Christ Jesus.
