The kingdom of heaven is like to a grain of mustard seed,
The mustard seed
I. The kingdom of heaven in the world is like a mustard seed sown in the ground, both in the smallness of its beginning and the greatness of its increase. The first promise given at the gate of Eden contained the gospel as a seed contains the tree. Never to human eye did the seed seem smaller than at the coming of Christ; the infant in a manger.
II. The kingdom of heaven Is A human heart is like a mustard seed, both in the smallness of its beginning and the greatness of its increase. In the design of God moral qualities hold the first place, physical magnitude is subordinate and instrumental. Origin imperceptible, result great, small on earth, it will be great in heaven. From the diminutive life of grace, the life of glory will grow. The kingdom of darkness also grows gradually from small to great; the first sin a small seed. (W. Arnot.)
A great growth from a small seed
The operation of the same law may be observed in later ages. In the Popish convent at Erfurt a studious young monk sits alone in his cell, earnestly examining an ancient record. The student is Luther, and the book the Bible. He has read many books before, but his reading has never made him wretched till now. In other books he saw other people; but in this book for the first time he saw himself. His own sin, when conscience was quickened and enlightened to discern it, became a burden heavier than he could bear. For a time he was in a horror of rent darkness; but when at last he found “the righteousness which is of God by faith,” he grew hopeful, happy, and strong. Here is a living seed, but it is very small: an awakened, exercised, conscientious, believing monk, is an imperceptible atom which superstitious multitudes, and despotic princes, and a persecuting priesthood will overlay and smother, as the heavy furrow covers the microscopic mustard-seed. But the living seed burst, and sprang, and pierced through all these coverings. How great it grew and how far it spread history tells to-day. We have cause to thank God for the greatness of the Reformation, and to rebuke ourselves for its smallness. (W. Arnot.)
The grain of mustard seed
I. We are taught by nature that small beginnings are, under God, productive of great ends.
II. We are taught it in the kingdom of providence.
III. We are taught it in the kingdom of grace. In the change produced upon the human heart. In the progress of the gospel (Psalms 72:16). (J. Campbell.)
The mustard seed
The kingdom of heaven.
I. Its present apparent insignificance.
II. Its vitality.
III. Its future grandeur. It might seem less likely to prevail and to become a universal benefit, than some other contemporary systems or influences. Christ, as a Jew belonged to the exclusive people. He was rejected by His own people. The few who were attached to Him misunderstood His teaching. After the resurrection His kingdom became slightly more visible. But our Lord was confident even under adverse conditions; His truth was of the nature of a seed. What is the vital element in Christianity but the wisdom and beauty of His teaching. Not the holiness of His life, or the love He showed, but the revelation of God in Him which draws men to Him; in His death our Lord points to the eventual greatness of His kingdom. It has indeed become a tree. To all disheartened in work; we must not measure work by size but by vitality. Have we joined the Church because it is large or because it is living. (M. Dods, D. D.)
