Luke 17:5-10

The apostles said to the Lord, Increase our faith (that trust and confidence that spring from our belief in God). And the Lord answered, If you had faith (trust and confidence in God) even [so small] like a grain of mustard seed, you could say to this mulberry tree, Be pulled up by the roots, and be planted in the sea, and it would obey you. Will any man of you who has a servant plowing or tending sheep say to him when he has come in from the field, Come at once and take your place at the table? Will he not instead tell him, Get my supper ready and gird yourself and serve me while I eat and drink; then afterward you yourself shall eat and drink? Is he grateful and does he praise the servant because he did what he was ordered to do? Even so on your part, when you have done everything that was assigned and commanded you, say, We are unworthy servants [possessing no merit, for we have not gone beyond our obligation]; we have [merely] done what was our duty to do.
