The Mustard-Seed
Luke 13:18-19
Then said he, To what is the kingdom of God like? and whereunto shall I resemble it?…


"The kingdom of heaven is like to a grain of mustard-seed — which indeed is is the least of all seeds." It is no exception to the law of growth which prevails throughout nature, and exemplifies how what is mightiest is often the product of what is apparently feeblest. Not only the giant oak, capable of defying the fiercest storms, but whole forests which yield materials for a nation's fleets, may have lain wrapped up within a single tiny acorn. In history, whatever has been most enduring and has exerted most influence, has been born in obscurity and feebleness, and grown up by almost imperceptible stages — whereas, whatever has, like the gourd of Jonah, arisen to its full height of a sudden, has withered and died away with the same rapidity that it arose. But Christianity is the most striking instance of the kind. Its fountain-head is the manger of a stable in a small Judeau town. There is a strange unobtrusiveness about the character and mission of the Author and Finisher of our faith. When we know who He was, the only begotten Son of God, and what His purpose was — the salvation of the world — we might expect to see Him take up a position full in the world's view, attracting to Himself man's whole attention, making kings His deputies, and philosophers His apostles, and orators His heralds, and armed captains His attendants. But no! the manger of a stable was His cradle — poverty, hard labours, great sorrows, keen sufferings, were His constant companions. It was the little seed-corn which had to be dropped into the ground and die ere the earth could bear a harvest of righteousness and peace. It was that by the preaching of which a few poor, illiterate Galilean fishermen were called upon to brave anal overcome the opposition which all the wealth, authority, antiquity, military force, taste, and philosophy, as well as ignorance and sin, of the world, could muster against them, to conquer the prejudices of the Jews, to undermine the superstitions under which Rome had grown up to be the mistress of the world, to confound the subtleties and wisdom of the Greeks, and to dispel the darkness of heathenism. It looked the most hopeless of tasks. There are instruction and warning for us in that. The gospel is the most emphatic protest against judging of things by their outward appearance. It is the solemn and decisive testimony of God to the superiority of spiritual principle over material magnificence. It casts down power and might to exalt spirit and truth. Many persons have an eye only to behold external and worldly greatness. There is no hope for any one, however, so long as he persists in looking at things with that dull, unspiritual eye. The gospel, in all that is distinctive of it, is spiritual, and can only be spiritually discerned. The parable having told us that the gospel in its origin is small, weak, and apparently insignificant, proceeds to speak of its growth, of its amazing progress. From the least of seeds it becomes the greatest of herbs; from an almost invisible grain it rises into a tree, where the birds of the air find shelter. It is unnecessary to insist that the history of the last eighteen hundred years has amply verified this representation. The Church, which at Pentecost only numbered a few score of persons, soon counted its adherents by thousands, burst the trammels of Judaism, and, even in the lifetime of its first apostles, established itself, without any other instrumentality than the foolishness of preaching, in all the large towns of the civilized world. All Europe and America are now more or less under its sway, and it is advancing with slow but sure steps to the conquest of the entire earth. It is more important to observe, as the text specially calls on us to do, that this long history is throughout a growth — that it may be fitly likened to a seed becoming a tree. Let us so look at it for a little, and see what lessons it has for our profit.

1. This is the first. The whole of Christianity, in so far as it is true, once lay in a small compass. All the truths, all the institutions, all the virtues which it embodies, may be traced back to a single life as their germ. The mustard. tree was wholly in the mustard-seed. The oak, great although it now is, once lay wrapped up entire in the acorn. All that properly belongs to it lay folded there. Nothing save what is foreign and hurtful, nothing save excrescences and parasites, have come from any other source. The influences of light and heat, and wind and dew, have only brought out what was there from the first, It is so, likewise, with Christianity. It has grown up through eighteen hundred years, it covers now a very large portion of the earth, but all that truly belongs to it even at this hour has sprung from the lowly life of Jesus. All that is good in its creeds, its institutions, the conduct it inspires, has germinated from some word of His — has lain as a thought in His mind or an affection in His heart; and whatever man has introduced of his own into religious belief or practice is only an excrescence, a parasite, a cause of weakness and decay. The lowliest life ever lived on earth has thus been infinitely the most fruitful. The least of all seeds has become the greatest among herbs.

2. The seed has not only all the rudiments of the future tree within it, but the life which unfolds them and sends out first the root and trunk, and then the branches, leaves, blossoms, and fruit. And the word of the gospel has likewise an indestructible principle of vitality, which cannot be repressed, cannot be arrested. It grows by the very necessity of its nature, under the influence of grace, just as the living seed, by the very necessity of its nature, under a genial sky cannot remain in the ground, but sends up blade and bud and branch. There is in this assertion no latent fatalism. Although the gospel has indeed been in history like a tree growing out of a living seed, it follows not that human will has had nothing to do with its progress. There is nothing in history, properly so called, with which human will has not had to do. Every improvement it tells of has been effected by human self-denial and toil. The country we live in was once covered with putrid morasses and gloomy forests, and yielded only a scanty and impure subsistence to a few hordes of wandering savages. Now its morasses are dried up, its forests cleared away, large cities stand thick strewn over it, its well-cultivated plains yield food enough for millions, and its industry produces an annual revenue the most enormous. What has wrought the change? Labour, and labour alone — labour of mind and of body. Not an inch of conquest has been won without mental exertion and physical toil, without anxious thought and an active hand. Religion is no exception to this rule, but its most striking example. It has had nobler and more numerous martyrs and missionaries — has called forth more heroic labours and costlier sacrifices — than all other causes together. And this is quite consistent with the fact that the gospel grows by a life of its own — that though man's labour is needed to apply and diffuse it, he neither makes it nor puts life and fruitfulness into it — that he receives it with these in itself, so that if he cast it into the ground it will spring and grow up of its own Divine energy, and according to its own Divine laws.

3. Growth implies increasing divergence and definiteness of parts and functions. It is a separation of the one into the many, a change from the simple to the complex, from the vague to the distinct. The seed out of which a plant issues is at first uniform in tissue and composition, but soon it divides into two parts, afterwards new contrasts appear in each of these, and it is by endless such changes that the complex combination of tissues and organs in a perfect plant is produced. While the parts are thus increased in number, each of them becomes more prominent in itself, more sharply distinguished from others, and more strictly confined to its own special use. Wherever growth takes place, this is the process traceable. It is what we see in every herb, in every animal, in civilization, in government, language, science, and art. Different as all these are in themselves, there is only the one way in which they can grow, in which they can truly progress. The kingdom of God conforms to the same conditions. Its history has consisted throughout in the evolution of doctrines, institutions, and modes of life, out of a very simple germ. Our elaborate systems of theological science so far as true, our manifold institutions for religious and benevolent purposes so far as good, our endlessly diversified modes of social being so far as right, are developments of the living word of the gospel, in which, however, they lay enfolded only as the tree in its seed, as results in their principle, as special and definite dogmas in broad and general statements. Those who say, "Let us cast to the winds our creeds, our systems, our definite dogmas, and return to the primitive simplicity of apostolic men," forget that God has not left it to the world's own will to return of a sudden, or to return at all, to the point from which it has taken eighteen centuries for it to advance. They might as well counsel us to throw off all the laws and institutions, all the countless arrangements of the elaborated civilization in which we live, and retrograde to the rude and simple life of the earliest dwellers in Asia and Europe. We are where we are, where long ages of thought and toil have placed us, and, even if ungrateful enough to desire it, there is no going back for us now.

4. The growth of the kingdom of God has been continuous. We may fail to measure its progress from day to day, because it is not rapid, but slow, not with observation, but without it. There is still another truth involved, and it is one which we must not despise because it is simple. Growth requires time. God has everywhere placed that as an inevitable separation between germination and maturity, between the seed and the perfect tree. Let us conform, then, to the condition. When we are despondent or angry because our labours in a Christian cause are not crowned with immediate success, we are no wiser than the little child who deposits a seed in the ground and is grieved not to see it springing up on the very day it has done so.
