THE MUSTARD SEED.
"Another parable put he forth unto them, saying, The kingdom of heaven is like to a grain of mustard seed, which a man took, and sowed in his field: which indeed is the least of all seeds: but when it is grown, it is the greatest among herbs, and becometh a tree, so that the birds of the air come and lodge in the branches thereof."[630]
This little story, addressed to the assembled multitude, must have set many thinking, because of the simplicity of the incident related and the thoroughly un-Jewish application made of it. To the mind taught by teachers of the time the kingdom was to be great and glorious from its beginning; it was to be ushered in by blare of trumpets and tramp of armies, with King Messiah at the head; yet this new Teacher spoke of it as having so small a beginning as to be comparable to a mustard seed. To make the illustration more effective He specified that the seed spoken of was "the least of all seeds." This superlative expression was made in a relative sense; for there were and are smaller seeds than the mustard, even among garden plants, among which rue and poppy have been named; but each of these plants is very small in maturity, while the well-cultivated mustard plant is one of the greatest among common herbs, and presents a strong contrast of growth from tiny seed to spreading shrub.
Moreover, the comparison "as small as a mustard seed" was in every-day use among Jews of the time. The comparison employed by Jesus on another occasion evidences the common usage, as when He said: "If ye have faith as a grain of mustard seed ... nothing shall be impossible unto you."[631] It should be known that the mustard plant attains in Palestine a larger growth than in more northerly climes.[632] The lesson of the parable is easy to read. The seed is a living entity. When rightly planted it absorbs and assimilates the nutritive matters of soil and atmosphere, grows, and in time is capable of affording lodgment and food to the birds. So the seed of truth is vital, living, and capable of such development as to furnish spiritual food and shelter to all who come seeking. In both conceptions, the plant at maturity produces seed in abundance, and so from a single grain a whole field may be covered.
