Matthew 13:31

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;

In this chapter, we have, I. The favour which Christ did to his countrymen in preaching the kingdom of heaven to them (Mat 13:1-2). He preached to them in parables, and here gives the reason why he chose that way of instructing (Mat 13:10-17). And the evangelist gives another reason (Mat 13:34, Mat 13:35). There are eight parables recorded in this chapter, which are designed to represent the kingdom of heaven, the method of planting the gospel kingdom in the world, and of its growth and success. The great truths and laws of that kingdom are in other scriptures laid down plainly, and without parables: but some circumstances of its beginning and progress are here laid open in parables. 1. Here is one parable to show what are the great hindrances of people's profiting by the word of the gospel, and in how many it comes short of its end, through their own folly, and that is the parable of the four sorts of ground, delivered (Mat 13:3-9). and expounded (Mat 13:18-23). 2. Here are two parables intended to show that there would be a mixture of good and bad in the gospel church, which would continue till the great separation between them in the judgment day: the parable of the tares put forth (Mat 13:24-30), and expounded at the request of the disciples (Mat 13:36-43); and that of the net cast into the sea (Mat 13:47-50). 3. Here are two parables intended to show that the gospel church should be very small at first, but that in process of time it should become a considerable body: that of the grain of mustard-seed (Mat 13:31, Mat 13:32), and that of the leaven (Mat 13:33). 4. Here are two parables intended to show that those who expect salvation by the gospel must be willing to venture all, and quit all, in the prospect of it, and that they shall be no losers by the bargain; th…

13:31-33 Jesus used surprising, evocative imagery in these parables, either to emphasize the inevitable growth of the Kingdom through proclamation of the gospel or, more probably, to emphasize the contrast between insignificant beginnings and glorious consummation, and to exhort the disciples to patience (see also 16:24–17:13).
