Thematic Bible: Supererogation

And thou, son of man, say unto the children of thy people, The righteousness of the righteous shall not deliver him in the day of his transgression; and as for the wickedness of the wicked, he shall not fall thereby in the day that he turneth from his wickedness; neither shall the righteous be able to live thereby in the day that he sinneth. When I say to the righteous that he shall certainly live, and he trusteth to his righteousness and doeth what is wrong, none of his righteous acts shall be remembered; but in his unrighteousness which he hath done, in it shall he die.

Thus ye also, when ye shall have done all things that have been ordered you, say, We are unprofitable bondmen; we have done what it was our duty to do. Verse ConceptsCommands, in NTServants, GoodDuty
