A heart across which all manner of other thoughts have right of way will remain unaffected by the voice of Jesus, if He spoke His sweetest, divinest tones, still more when He speaks but through some feeble man. The listener hears the words, but they never get farther than the drum of his ear. They lie on the surface of his soul, which is beaten hard, and is non-receptive. How many there are who have been listening to the preaching of the Gospel, which is in a true sense the sowing of the seed, all their lives, and have never really been in contact with it! Tramp, tramp, go the feet across the path, heavy drays of business, light carriages of pleasure, a never-ending stream of traffic and noise like that which pours day and night through the streets of a great city, and the result is complete insensibility to Christ's voice.
If one could uncover the hearts of a congregation, how many of them would be seen to be occupied with business or pleasures, or some favourite pursuit, even while they sit decorously in their pews! How many of them hear the preacher's voice without one answering thought or emotion! How many could not for their lives tell what his last sentence was! No marvel, then, that, as soon as its last sound has ceased, down pounce a whole covey of light-winged fancies and occupations, and carry off the poor fragments of what had been so imperfectly heard. One wonders what percentage of remembrances of a sermon is driven out of the hearers' heads in the first five minutes of their walk home, by the purely secular conversation into which they plunge so eagerly.
II. The next class of hearers is represented by seed which has had somewhat better fate, inasmuch as it has sunk some way in, and begun to sprout. The field, like many a one in hilly country, had places where the hard pan of underlying rock had only a thin skin of earth over it. Its very thinness helped quick germination, for the rock was near enough to the surface to get heated by the sun. So, with undesirable rapidity, growth began, and shoots appeared above ground before there was root enough made below to nourish them. There was only one possible end for such premature growth--namely, withering in the heat. No moisture was to be drawn from the shelf of rock, and the sun was beating fiercely down, so the feeble green stem drooped and was wilted.
It is the type of emotional hearers, who are superficially touched by the Gospel, and too easily receive it, without understanding what is involved. They take it for theirs 'with joy,' but are strangers to the deep exercises of penitence and sorrow which should precede the joy. 'Lightly come, lightly go,' is true in Christian life as elsewhere. Converts swiftly made are quickly lost. True, the most thorough and permanent change may be a matter of a moment; but, if so, into that moment emotions will be compressed like a great river forced through a mountain gorge, which will do the work of years.
Such surface converts fringe all religious revivals. The crowd listening to our Lord was largely made up of them. These were they who, when a ground of offence arose, 'went back, and walked no more with Him.' They have had their successors in all subsequent times of religious movement. Light things are caught up by the wind of a passing train, but they soon drop to the ground again. Emotion is good, if there are roots to it. But 'these have no root.' The Gospel has not really touched the depths of their natures, their wills, their reason, and so they shrivel up when they have to face the toil and self-sacrifice inherent in a Christian life.
III. The third parcel of seed advanced still farther. It rooted and grew. But the soil had other occupants. It was full of seeds of weeds and thorns (not thorn _bushes_). So the two crops ran a race, and as ill weeds grow apace, the worse beat, and stifled the green blades of the springing corn, which, hemmed in and shut out from light and air, came to nothing.
