'The kingdom of heaven is like unto leaven, which a woman took, and bid to three measures of meal, till the whole was leavened.'--MATT. xiii. 33.
How lovingly and meditatively Jesus looked upon homely life, knowing nothing of the differences, the vulgar differences, between the small and great! A poor woman, with her morsel of barm, kneading it up among three measures of meal, in some coarse earthenware pan, stands to Him as representing the whole process of His work in the world. Matthew brings together in this chapter a series of seven parables of the kingdom, possibly spoken at different times, and gathered here into a sequence and series, just as he has done with the great procession of miracles that follows the Sermon on the Mount, and just as, perhaps, he has done with that sermon itself. The two first of the seven deal with the progress of the Gospel in individual minds and the hindrances thereto. Then there follows a pair, of which my text is the second, which deal with the geographical expansion of the kingdom throughout the world, in the parable of the grain of mustard-seed growing into the great herb, and with the inward, penetrating, diffusive influence of the kingdom, working as an assimilating and transforming force in the midst of society.
I do not purpose to enter now upon the wide and difficult question of the relation of the kingdom to the Church. Suffice it to say that the two terms are by no means synonymous, but that, at the same time, inasmuch as a kingdom implies a community of subjects, the churches, in the proportion in which they have assimilated the leaven, and are holding fast by the powers which Christ has lodged within them, are approximate embodiments of the kingdom. The parable, then, suggests to us, in a very striking and impressive form, the function and the obligations of Christian people in the world.
Let me deal, in a purely expository fashion, with the emblem before us.
'The kingdom of heaven is like leaven.' Now of course, leaven is generally in Scripture taken as a symbol of evil or corruption. For example, the preliminary to the Passover Feast was the purging of the houses of the Israelites of every scrap of evil ferment, and the bread which was eaten on that Feast was prescribed to be unleavened. But fermentation works ennobling as well as corruption, and our Lord lays hold upon the other possible use of the metaphor. The parable teaches that the effect of the Gospel, as ministered by, and residing in, the society of men, in whom the will of God is supreme, is to change the heavy lump of dough into light, nutritious bread. There are three or four points suggested by the parable which I could touch upon; and the first of them is that significant disproportion between the apparent magnitude of the dead mass that is to be leavened, and the tiny piece of active energy which is to diffuse itself throughout it.
We get there a glimpse into our Lord's attitude, measuring Himself against the world and the forces that were in it. He knows that in Him, the sole Representative, at the moment, of the kingdom of heaven upon earth--because in Him, and in Him alone, the divine will was, absolutely and always, supreme--there lie, for the time confined to Him, but never dormant, powers which are adequate to the transformation of humanity from a dead, lumpish mass into an aggregate all-penetrated by a quickening influence, and, if I might so say, fermented with a new life that He will bring. A tremendous conception, and the strange thing about it is that it looks as if the Nazarene peasant's dream was going to come true! But He was speaking to the men whom He was charging with a delegated task, and to them He says, 'There are but twelve of you, and you are poor, ignorant men, and you have no resources at your back, but you have Me, and that is enough, and you may be sure that the tiny morsel of yeast will penetrate the whole mass.' Small beginnings characterise the causes which are destined to great endings; the things that are ushered into the world large, generally grow very little further, and speedily collapse. 'An inheritance may be gotten hastily at the beginning, but the end shall not be blessed.' The force which is destined to be worldwide, began with the one Man in Nazareth, and although the measures of meal are three, and the ferment is a scrap, it is sure to permeate and transform the mass.
