Romans 2
14 Ref (for when Gentiles who don't have the law do by nature the things of the law, these, not having the law, are a law to themselves,
15 Ref in that they show the work of the law written in their hearts, their conscience testifying with them, and their thoughts among themselves accusing or else excusing them)
16 Ref in the day when God will judge the secrets of men, according to my Gospel, by Jesus Christ.
