Luke 17:5-10
17:5 The apostles said to the Lord, “Increase our faith!”
17:6 So the Lord replied, “If you had faith the size of a mustard seed, you could say to this black mulberry tree, ‘Be pulled out by the roots and planted in the sea,’ and it would obey you.
17:7 “Would any one of you say to your slave who comes in from the field after plowing or shepherding sheep, ‘Come at once and sit down for a meal’?
17:8 Won’t the master instead say to him, ‘Get my dinner ready, and make yourself ready to serve me while I eat and drink. Then you may eat and drink’?
17:9 He won’t thank the slave because he did what he was told, will he?
17:10 So you too, when you have done everything you were commanded to do, should say, ‘We are slaves undeserving of special praise; we have only done what was our duty.’”
