Luke 17:5-10 - Faith And Duty

5 And the apostles said to the Lord, Increase our faith. And the Lord said,

6 If ye had faith as a grain of mustard seed, ye might say to this sycamine tree, Be thou rooted up, and be thou planted in the sea; and it should obey you.

7 But which of you having a servant plowing or feeding cattle, will say to him as soon as he cometh from the field, Come and sit down to table? 8 And will not rather say to him, Make ready wherewith I may sup, and gird thyself and serve me till I have eaten and drunk, and afterward thou shalt eat and drink? 9 Doth he thank that servant because he did the things that were commanded him? 10 I think not. So likewise ye, when ye have done all the things that are commanded you, say, We are but unprofitable servants: we have done what was our duty to do.
