The first thing which we ought to notice in these verses is the striking question with which our Lord winds up the seven wonderful parables of this chapter: He said, “Have ye understood all these things?”

Personal application has been called the “soul” of preaching. A sermon without application is like a letter posted without a direction: it may be well written, rightly dated and duly signed; but it is useless, because it never reaches its destination. Our Lord’s inquiry is an admirable example of real heart-searching application: “Have ye understood?”

The parables of the “treasure hidden in a field,” and the “merchant man seeking goodly pearls,” appear intended to convey one the same lesson. They vary, no doubt, in one striking particular: the “treasure” was found of one who does not seem to have sought it; the “pearl” was found of one who was actually seeking pearls. But the conduct of the finders, in both cases, was precisely alike: both “sold all” to make the thing found their own property; and it is exactly at this point that the instruction of both parables agrees.

These two parables are meant to teach us, that men who are really convinced of the importance of salvation will give up everything to win Christ and eternal life.

The parable of the “wheat and tares,” which occupies the chief part of these verses, is one of peculiar importance in the present day. It is eminently calculated to correct the extravagant expectations in which many Christians indulge, as to the effect of missions abroad, and of preaching the Gospel at home. May we give it the attention which it deserves!

In the first place, this parable teaches us, that good and evil will always be found together in the professing church, until the end of the world.

The visible Church is set before us as a mixed body: it is a vast “field” in which “wheat and tares” grow side by side. We must expect to find believers and unbelievers, converted and unconverted, “the children of the kingdom and the children of the wicked one” all mingled together in every congregation of baptized people.

The chapter which these verses begin is remarkable for the number of parables which it contains. Seven striking illustrations of spiritual truth are here drawn by the great Head of the Church from the book of nature. By so doing He shows us that religious teaching may draw help from everything in creation. Those that would “find out acceptable words,” should not forget this. (Eccles. 12:10)

The parable of the Sower, which begins this chapter, is one of those parables which admit of a very wide application. It is being continually verified under our own eyes. Wherever the Word of God is preached or expounded and people are assembled to hear it, the sayings of our Lord in this parable are found to be true. It describes what goes on, as a general rule, in all congregations.
