Luke 17:7-10

“Which of you, having a slave plowing or tending sheep, will say to him when he has come in from the field, ‘Come immediately and sit down to eat’? But will he not say to him, ‘Prepare something for me to eat, and properly clothe yourself and serve me while I eat and drink; and afterward you may eat and drink’? He does not thank the slave because he did the things which were commanded, does he? So you too, when you do all the things which are commanded you, say, ‘We are unworthy slaves; we have done only that which we ought to have done.’ ”
