15 They show that the work of the law is written on their hearts, while their conscience also bears witness, and their conflicting thoughts accuse or even excuse them
16 on that day when, according to my gospel, God judges the secrets of men by Christ Jesus.
17 But if you call yourself a Jew and rely on the law and boast in God
18 and know his will and approve what is excellent, because you are instructed from the law;
19 and if you are sure that you yourself are a guide to the blind, a light to those who are in darkness,
20 an instructor of the foolish, a teacher of children, having in the law the embodiment of knowledge and truth—
21 you then who teach others, do you not teach yourself? While you preach against stealing, do you steal?
