Luke 17:5-10Revised Standard Version Catholic Edition (RSVCE)
5 The apostles said to the Lord, “Increase our faith!” 6 And the Lord said, “If you had faith as a grain of mustard seed, you could say to this sycamine tree, ‘Be rooted up, and be planted in the sea,’ and it would obey you.
7 “Will any one of you, who has a servant plowing or keeping sheep, say to him when he has come in from the field, ‘Come at once and sit down at table’? 8 Will he not rather say to him, ‘Prepare supper for me, and gird yourself and serve me, till I eat and drink; and afterward you shall eat and drink’? 9 Does he thank the servant because he did what was commanded? 10 So you also, when you have done all that is commanded you, say, ‘We are unworthy servants; we have only done what was our duty.’”
