Why are certain men so extremely rocky? Some are so from a peculiar stolidity of nature. There are many people in the world whom you cannot very well move, they have a great deal of granite in their constitution, and are more nearly related to Mr. Obstinate than to Mr. Pliable. Now, I do not think badly of these people, because one knows what it is to preach to an excitable people, and to get them all stirred, and to know that in the end they are none the better; whereas some of the more stolid and immovable people when they are moved are moved indeed; when they do feel they feel intensely, and they retain any impression that is made. A little chip made in granite by very hard blows will abide there, while the lashing of water, which is easy enough, will leave no trace even for a moment. It is a grand thing to get hold of a fine piece of rock and to exercise faith about it. The Lord's own hammer has mighty power to break, and in the breaking great glory comes to the Most High.
Worse still, certain men are hard because of their infidelity—not heart-infidelity all of it, but an infidelity which springs out of a desire not to believe, which has helped them to discover difficulties. These difficulties exist, and were meant to exist, for there would be no room for faith if everything were as plain as the nose on one's face. These persons have gradually come to doubt, or to think that they doubt, essential truths, and this renders them impervious to the gospel of Christ.
A much more numerous body are orthodox enough, but hard-hearted for all that. Worldliness hardens a man in every way. It often dries up all charity to the poor, because the man must make money, and he thinks that the poor-rates are sufficient excuse for neglecting the offices of charity. He has no time to think of the next world; he must spend all his thoughts upon the present one. Money is tight, and therefore he must hold it tight; and when money brings in little interest, he finds therein a reason for being the more niggardly. He has no time for prayer, he must get down to the counting-house. He has no time for reading his Bible, his ledger wants him. You may knock at his door, but his heart is not at home; it is in the counting-house, wherein he lives and moves and has his being. His god is his gold, his bliss is his business, his all in all is himself. What is the use of preaching to him? As well may horses run upon a rock, or oxen drag a plough across a field sheeted with iron a mile thick.
With some, too, there is a hardness, produced by what I might almost call the opposite of stern worldliness, namely, a general levity. They are naturally butterflies flitting about and doing nothing. They never think, or want to think. Half a thought exhausts them, and they must needs be diverted, or their feeble minds will utterly weary. They live in a round of amusement. To them the world is a stage, and all the men and women only players. It is of little use to preach to them; there is no depth of earth in their superficial nature; beneath a sprinkling of shifting worthless sand lies an impenetrable rock of utter stupidity and senselessness. I might thus multiply reasons why some are harder than others, but it is a well-assured fact that they are so, and there I leave the matter.
III. I shall now ask everybody to judge whether the running of horses upon a rock and the ploughing there with oxen shall always be continued. I assert that it is unreasonable to expect that God's servants should always continue to labor in vain. These people have been preached to, taught, instructed, admonished, expostulated with, and advised; shall this unrecompensed work be always performed? We have given them a fair trial; what do reason and prudence say? Are we bound to persevere till we are worn out by this unsuccessful work? We will ask it of men who plough their own farms; do they recommend perseverance when failure is certain? Shall horses run upon the rock? Shall one plough there with oxen? Surely not for ever.
I think we shall all agree that labor in vain cannot be continued for ever if we consider the ploughman. He does not want to be much considered; but still his Master does not overlook him. See how weary he grows when the work discourages him. He goes to his Master with, "Who hath believed our report, and to whom is the arm of the Lord revealed?" "Why hast thou sent me," says he, "to a people that have ears but hear not? They sit as thy people sit, and they hear as thy people hear, and then they go their way and they forget every word that is spoken, and they obey not the voice of the Lord." See how disappointed the preacher becomes. It is always hard work when you appear to get no forwarder, although you do your utmost. No man, whoever he may be, likes to be set upon work which appears to be altogether a waste of time and effort. To his own mind it seems to have a touch of the ridiculous about it, and he fears that he will be despised of his fellows for aiming at the impossible. Shall it always be the lot of God's ministers to be trifled with? Will the great Husbandman bid his ploughmen spill their lives for nought? Must his preachers continue to cast pearls before swine? If the consecrated workers are so bidden by their Lord they will persevere in their painful task; but their Master is considerate of them, and I ask you also to consider whether it is reasonable to expect a zealous heart to be for ever occupied with the salvation of those who never respond to its anxiety? Shall the horses always plough upon the rock? Shall the oxen always labor there?
Again, there is the Master to be considered. The Lord—is he always to be resisted and provoked? Many of you have had eternal life set before you as the result of believing in Jesus; and you have refused to believe. It is a wonder that my Lord has not said to me, "You have done your duty with them; never set Christ before them again; my Son shall not be insulted." If you offer a beggar in the street a shilling and he will not have it, you cheerfully put it into your purse and go your way; you do not entreat him to have his wants relieved. But, behold, our God in mercy begs sinners to come to him, and implores them to accept his Son. In his condescension he even stands like a salesman in the market, crying, "Ho, every one that thirsteth, come ye to the waters, and he that hath no money; come, buy wine and milk without money and without price." In another place he says of himself, "All day long have I stretched out my hands to a disobedient and gainsaying generation." If the Lord of mercy has been refused so long in the sight of you who reverence him, does not some indignation mingle with your pity, and while you love sinners and would have them saved, do you not feel in your heart that there must be an end to such insulting behavior? I ask even the careless to think of the matter in this light, and if they do not respect the ploughman, yet let them have regard to his Master.
And then, again, there are so many other people who are needing the gospel, and who would receive it if they had it, that it would seem to be wise to leave off wearying oneself about those who despise it. What did our Lord say? He said that if the mighty things which had been done in Bethsaida and Chorazin had been done in Tyre and Sidon, they would have repented. What is more wonderful still, he says that if he had wrought the same miracles in Sodom and Gomorrah which were wrought in Capernaum, they would have repented in sackcloth and ashes. Does it not occur to us at once to give the word to those who will have it, and leave the despisers to perish in their own wilfulness? Does not reason say, "Let us send this medicine where there are sick people who will value it?" Thousands of people are willing to hear the gospel. See how they crowd wherever the preacher goes—how they tread upon one another in their anxiety to listen to him; and if these people who hear him every day will not receive his message, "in God's name," saith he, "let me go where there is a probability of finding soil that can be ploughed." "Shall horses run upon the rock? Will one plough there with oxen?" Must I work always where nothing comes of it? Does not reason say, let the word go to China, to Hindostan, or to the utmost parts of the earth, where they will receive it; for those who have it preached in the corners of their streets despise it?
I shall not lengthen this argument, but shall solemnly put the question again. Would any of you continue to pursue an object when it has proved to be hopeless? Do you wonder that when the Lord has sent his servants to speak kind, gracious, tender words, and men have not heard, he says to them, "They are joined unto their idols; let them alone"? There is a boundary to the patience of men, and we soon arrive at it; and assuredly there is a limit, though it is long before we outrun it, to the patience of God. "At length," he says, "it is enough. My Spirit shall no longer strive with them." If the Lord says this can any of us complain? Is not this the way of wisdom? Does not prudence itself dictate it? Any thoughtful mind will say, "Ay, ay, a rock cannot be ploughed for ever."
IV. Fourthly. There must be an alteration, then, and that speedily. The oxen shall be taken off from such toil. It can be easily done, and done soon. It can be effected in three ways.
