Thematic Bible: Supererogation

And you, son of man, say to the children of your people, The righteousness of the upright man will not make him safe in the day when he does wrong; and the evil-doing of the evil man will not be the cause of his fall in the day when he is turned from his evil-doing; and the upright man will not have life because of his righteousness in the day when he does evil. When I say to the upright that life will certainly be his; if he puts his faith in his righteousness and does evil, not one of his upright acts will be kept in memory; but in the evil he has done, death will overtake him.

In the same way, when you have done all the things which are given you to do, say, There is no profit in us, for we have only done what we were ordered to do. Verse ConceptsCommands, in NTServants, GoodDuty
