Luke 17:7-10 - Unworthy Servants
7 But which of you, having a servant who is ploughing or keeping sheep, will say to him, when he comes in from the field, Come now and be seated and have a meal, 8 Will he not say, Get a meal for me, and make yourself ready and see to my needs till I have had my food and drink; and after that you may have yours? 9 Does he give praise to the servant because he did what was ordered? 10 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.
