The whole thing turns on the distinction between earnest inquirers and careless hearers. There must have been many of the latter in His audience, for this was no selected company, like that which listened to the Sermon on the Mount. The earnest inquirer has ears to hear; the other has not. The difference this makes is most strikingly set forth in the strong declaration: "Whosoever hath, to him shall be given, and he shall have more abundance: but whosoever hath not, from him shall be taken away even that he hath,"--that is, instead of being the better for what he has heard, he is the worse; not apprehending the truth, he is only perplexed and confused by it, and instead of going away enriched, he is poorer than ever. What, then, is to be done? If, instead of doing the people good, it only does them harm, why try to teach them at all? Why not let them alone, till they come with ears to hear, ready to receive? Happily this sad alternative is not the only resource. The truth may be put in such a way that it has both a shell and kernel of meaning; and the kernel may be so inclosed in the shell that it can be kept safely there, ready for the time when the inner fruit, which is the true food of the soul, can be used. For this purpose the parable is pre-eminently serviceable. The shell of meaning is so simple and familiar, that even a child can understand it; being of the nature of a story, it is very easily remembered; and connected as it is with that which is frequently observed, it will come up again and again to the minds of those in whom the thought has been lodged; so that, even if, on first hearing it, there is no possibility of understanding its deep spiritual significance, the time may come when it will flash upon the spirit the light which has been concealed within and so preserved from waste. Take this parable of "The Sower" as an illustration. The disciples, having ears to hear, were ready to get the good of it at once, so to them He expounds it (vv. 18-23) on the spot. The rest were not ready to receive and apply it. Having ears (but not ears to hear), they heard not; but did it follow from this that it was useless, even worse than useless, to give it them? Had the teaching been direct, it would have been so; for they would have heard and rejected, and that would have been the last of it. But put as it was in parabolic form, while they were not prepared to understand and apply it then, they could not but carry it away with them; and, as they walked the fields, and observed the birds picking the seeds from the trodden field-paths, or the tiny plants withering on the rocky ledges, or the springing wheat strangled with rank growths of thorns, or the healthy growing wheat plant, or later in the season the rich golden grain on the good soil, they would have opportunity after opportunity of getting a glimpse of the truth, and finding that which at the first they were so unprepared to receive.
