Luke 17:4-10

Even if he sins against you seven times a day, and returns to you seven times and says, ‘I repent,’ you must forgive him [that is, give up resentment and consider the offense recalled and annulled].” The apostles said to the Lord, “Increase our faith [our ability to confidently trust in God and in His power].” And the Lord said, “If you have [confident, abiding] faith in God [even as small] as a mustard seed, you could say to this mulberry tree [which has very strong roots], ‘Be pulled up by the roots and be planted in the sea’; and [if the request was in agreement with the will of God] it would have obeyed you. [Matt 17:20; Mark 11:23; 1 John 5:14] “Which of you who has a servant plowing or tending sheep will say to him when he comes in from the field, ‘Come at once and sit down to eat?’ Will he not instead say to him, ‘Prepare something for me to eat, and appropriately clothe yourself [for service] and serve me while I eat and drink; then afterward you may eat and drink?’ He does not thank the servant just because he did what he was ordered to do, does he? So you too, when you have done everything that was assigned and commanded you, say, ‘We are unworthy servants [undeserving of praise or a reward, for we have not gone beyond our obligation]; we have merely done what we ought to do.’ ”
