Romans 2:15; Romans 9:1; Romans 13:5

15 in that they show the work of the Law written in their hearts, their conscience bearing witness and their thoughts alternately accusing or else defending them,

1 I am telling the truth in Christ, I am not lying, my conscience testifies with me in the Holy Spirit,

5 Therefore it is necessary to be in subjection, not only because of wrath, but also for conscience' sake.
