Romans 2:13-16

¹³for it is not the hearers of the Law who are righteous before God, but the doers of the Law who will be justified. ¹⁴For when Gentiles who do not have the Law instinctively perform the requirements of the Law, these, though not having the Law, are a law to themselves, ¹⁵in that they show the work of the Law written in their hearts, their conscience testifying and their thoughts alternately accusing or else defending them, ¹⁶on the day when, according to my gospel, God will judge the secrets of mankind through Christ Jesus.
