Luke 17:7-10 - Unworthy Servants
7 But which of you having a servant plowing, or feeding cattle, will say to him immediately, when he is come from the field, Go and sit down to eat? 8 And will not rather say to him, Make ready wherewith I may sup, and gird thyself, and serve me, till I have eaten and drank; and afterward thou shalt eat and drink? 9 Doth he thank that servant, because he did the things that were commanded him? I suppose not. 10 So likewise ye, when ye shall have done all the things which are commanded you, say, We are unprofitable servants: we have done that which it was our duty to do.
