Romans 2:14

12 for as many as without law did sin, without law also shall perish, and as many as did sin in law, through law shall be judged,

13 for not the hearers of the law [are] righteous before God, but the doers of the law shall be declared righteous: --

14 For, when nations that have not a law, by nature may do the things of the law, these not having a law -- to themselves are a law;

15 who do shew the work of the law written in their hearts, their conscience also witnessing with them, and between one another the thoughts accusing or else defending,

16 in the day when God shall judge the secrets of men, according to my good news, through Jesus Christ.
