But when it is sown, it grows up, and becomes greater than all plants, and shoots out great branches; so that the fowls of the air may lodge under the shadow of it.
All Commentaries on Mark 4:32 Go To Mark 4
Ambrose of Milan
AD 397
Its seed is indeed very plain, and of little value; but if bruised or crushed it shows forth its power. So faith first seems a simple thing; but if it is bruised by its enemies it gives forth proof of its power, so as to fill others who hear or read of it with the odor of its sweetness. Our martyrs, Felix, Nabor and Victor, possessed the sweet odor of faith; but they dwelt in obscurity. When the persecution came, they laid down their arms, and bowed their necks, and being stricken by the sword they diffused to all the ends of the earth the grace of their martyrdom…. The Lord himself is the grain of mustard seed. He was without injury; but the people were unaware of him as a grain of mustard seed of which they took no notice. He chose to be bruised, that we might say: “For we are the good odor of Christ unto God.”
