Luke 17:7-10

Luke 17:7-10
7 But which of you, having a servant plowing or feeding cattle, would say to him, as he was returning from the field, 'Come in immediately; sit down to eat,'
8 and would not say to him: 'Prepare my dinner; gird yourself and minister to me, while I eat and drink; and after these things, you shall eat and drink?'
9 Would he be grateful to that servant, for doing what he commanded him to do?
10 I think not. So too, when you have done all these things that have been taught to you, you should say: 'We are useless servants. We have done what we should have done.' "
