Luke 17:8

6The Lord said, “If you had faith like a grain of mustard seed, you would tell this sycamore tree, ‘Be uprooted and be planted in the sea,’ and it would obey you.

7But who is there among you, having a servant plowing or keeping sheep, that will say when he comes in from the field, ‘Come immediately and sit down at the table’?

8Wouldn’t he rather tell him, ‘Prepare my supper, clothe yourself properly, and serve me while I eat and drink. Afterward you shall eat and drink’?

9Does he thank that servant because he did the things that were commanded? I think not.

10Even so you also, when you have done all the things that are commanded you, say, ‘We are unworthy servants. We have done our duty.’”
