“Suppose one of you has a servant plowing or looking after the sheep. Will he say to the servant when he comes in from the field, ‘Come along now and sit down to eat’?
Won’t he rather say, ‘Prepare my supper, get yourself ready and wait on me while I eat and drink; after that you may eat and drink’?
Will he thank the servant because he did what he was told to do?
So you also, when you have done everything you were told to do, should say, ‘We are unworthy servants; we have only done our duty.’ ”
