Romans 2:12-16

¹²For as many as have sinned without the law will also perish without the law, and as many as have sinned with respect to the law will be judged by the law.

¹³For it is not the hearers of the law who are righteous before God, but it is the doers of the law who will be justified.

¹⁴For when Gentiles, who do not have the law, do by nature the things of the law, they are a law to themselves, although they do not have the law.

¹⁵By this they show that the actions required by the law are written in their hearts. Their conscience also bears witness to them, and their own thoughts either accuse or defend them to themselves

¹⁶and also to God. That will happen on the day when God will judge the secrets of all people, according to my gospel, through Jesus Christ.
