In response, the Lord directed their attention to the tremendous power of faith, which, even in its nascent state—like a tiny seed—can yield extraordinary results: If you had faith the size of a mustard seed, you could command this mountain, ‘Be lifted up and thrown into the sea,’ and it would obey you. The Saviour had previously conveyed this same message to His disciples (Matt. 17:20) and reiterated it later (21:21). By likening the Kingdom of Heaven and faith to a mustard seed (13:31-32), He aimed to inspire the notion of faith's continual growth and deepening within the human soul. The disciples were urged to nurture faith within themselves, allowing it to gradually and unobtrusively envelop their entire being. However, the Lord cautioned His followers against pride in the results of their faith and self-admiration stemming from good deeds. He illustrated humility through a relatable scenario: ‘Which of you has a servant who tends sheep or plows, and when he comes in from the field says to him, “Come at once and sit down to eat"? Will he not rather say to him, “Prepare something for me to eat, and when you are finished, serve me while I eat and drink; then afterward you may eat and drink"? Does he thank the servant because he did what he was told? So you also, when you have done everything you were told to do, should say, “We are unworthy servants; we have only done our duty.”’ Although, notes Monk Neil of Sinai, fulfilling obligations does allow for joy at having done one’s duty, it does not justify self-exaltation. A debt exists to be repaid, not an arbitrary gift, and it is inappropriate for one who has fulfilled what belongs to Christ to boast as if they are a benefactor, magnifying their contributions in a manner that prompts required gratitude.
