According to Matthew and Luke, Christ explains the parable to his disciples simply, and unaccompanied by a reproof; but according to Mark, he indirectly blames them for being slow of apprehension, because those who were to be the teachers of all did not run before others. The general truth conveyed is, that the doctrine of the Gospel, when it is scattered like seed, is not everywhere fruitful; because it does not always meet with a fertile and well cultivated soil. He enumerates four kinds of hearers: the first of which do not receive the seed; the second appear, indeed, to receive it, but in such a manner that it does not take deep root; in the third, the corn is choked; and so there remains a fourth part, which produces fruit. Not that one hearer only out of four, or ten out of forty, embrace the doctrine, and yield fruit; for Christ did not intend here to fix down an exact number, or to arrange the persons, of whom he speaks, in equal divisions; and, indeed, where the word is sown, the produce of faith is not always alike, but is sometimes more abundant, and at other times more scanty. He only intended to warn us, that, in many persons, the seed of life is lost on account of various defects, in consequence of which it is either destroyed immediately, or it withers, or it gradually degenerates. That we may derive the greater advantage from this warning, we ought to bear in mind, that he makes no mention of despisers who openly reject the word of God, but describes those only in whom there is some appearance of docility. But if the greater part of such men perish, what shall become of the rest of the world, by whom the doctrine of salvation is openly rejected? I now come down to each class.

Now the parable is this, &c. "Or this is the sense of the parable", as the Arabic version renders it: "the seed is the word of God", the Gospel, as preached by Christ, his apostles, and faithful ministers, which has God for its author, is concerning the grace of God, and is what he blesses, and makes effectual to answer any good purpose.
