Marcos 4:28
But even in these things that are sought by human hands, a great part of divine benefits remain with us, so that even the grains themselves are produced while we are at rest. This is taught as an example of the proposed lesson, with the Lord saying: For the kingdom of God is like a man who throws seed upon the earth and then sleeps and rises, night and day, and the seed sprouts and grows, while he does not know how (Mark, IV, 26). For the earth produces fruit willingly, first grass, then ear, then full wheat in the ear. And when it has produced fruit, it immediately sends forth the sickle, for the harvest is at hand. Therefore, to you, o man, who sleep and know not its fruits, the earth produces them willingly. You sleep and rise, and marvel at the growth of wheat during the night. — The Six Days of Creation, Book 3, Chapter 10
Marcos 4:32
Now let us consider the nature of mustard, and the power of comparison. The mustard seed itself is certainly a cheap and simple thing: if it is ground, it releases its strength. Similarly, faith at first seems simple, but if it is tested by adversity, it reveals the grace of its virtue; so that it also fills others who either hear or read with the fragrance of itself. The mustard seed of our martyrs is Felix, Nabor, and Victor: they had the fragrance of faith, but it was hidden. Persecution came, they laid down their weapons, bowed their necks, and with a broken sword spread the grace of their martyrdom throughout the whole world, so that it may rightly be said: Their sound has gone out into all the earth. But faith is worn in one way, pressured in another, and sown in another. The Lord Himself is the grain of mustard seed. He was blameless from injury, but as the grain of mustard seed which the people had not crushed, he did not know. He preferred to be worn, so that we may say: "For we are the good odor of Christ unto God." — Commentary on Luke
