Read Romans 2 in full →14For when Gentiles who do not have 1the Law anaturally do the things of the Law, these, not having 2the Law, are a law to themselves, 15in that they demonstrate athe work of the Law written in their hearts, their conscience bearing witness and their thoughts alternately accusing or else defending them, 16on the day when, aaccording to my gospel, bGod will judge the secrets of men through Christ Jesus.
