Luke 17:5–10

And the apostles said to the Lord: Increase our faith. 6And the Lord said: If you had faith like to a grain of mustard seed, you might say to this mulberry tree: Be thou rooted up and be thou transplanted into the sea. And it would obey you. 7But which of you, having a servant ploughing or feeding cattle, will say to him, when he is come from the field: Immediately go. Sit down to meat. 8And will not rather say to him: Make ready my supper and gird thyself and serve me, whilst I eat and drink; and afterwards thou shalt eat and drink? 9Doth he thank that servant for doing the things which he commanded him? 10I think not. So you also, when you shall have done all these things that are commanded you, say: We are unprofitable servants; we have done that which we ought to do.
