Romans 2:14-16

Revised Standard Version

¹⁴ When Gentiles who have not the law do by nature what the law requires, they are a law to themselves, even though they do not have the law. ¹⁵ They show that what the law requires is written on their hearts, while their conscience also bears witness and their conflicting thoughts accuse or perhaps excuse them ¹⁶ on that day when, according to my gospel, God judges the secrets of men by Christ Jesus.
