Now the sense of duty exerts just this influence, upon sinful man. It opposes his wishes; it thwarts his inclination; it imposes a restraint upon his spontaneous desires and appetites. It continually hedges up his way, and seeks to stop him in the path of his choice and his pleasure. If his inclination were only in harmony with his duty; if his desires and affections were one with the law of God; there would be no restraint from the law. In this case, the sense of duty would be a joy and not a sorrow, because, in doing his duty, he would be doing what he liked. There are only two ways, whereby contentment can be introduced into the human soul. If the Divine law could be altered so that it should agree with man's sinful inclination, he could be happy in sin. The commandment having become like his own heart, there would, of course, be no conflict between the two, and he might sin on forever and lap himself in Elysium. And undoubtedly there are thousands of luxurious and guilty men, who, if they could, like the Eastern Semiramis, would make lust and law alike in their decree;[1] would transmute the law of holiness into a law of sin; would put evil for good, and good for evil, bitter for sweet and sweet for bitter; in order to be eternally happy in the sin that they love. They would bring duty and inclination into harmony, by a method that would annihilate duty, would annihilate the eternal distinction between right and wrong, would annihilate God himself. But this method, of course, is impossible. There can be no transmutation of law, though there can be of a creature's character and inclination. Heaven and earth shall pass away, but the commandment of God can never pass away. The only other mode, therefore, by which duty and inclination can be brought into agreement, and the continual sense of restraint which renders man so wretched be removed, is to change the inclination. The instant the desires and affections of our hearts are transformed, so that they accord with the Divine law, the conflict between our will and our conscience is at an end. When I come to love the law of holiness and delight in it, to obey it is simply to follow out my inclination. And this, we have seen, is to be happy.
But such is not the state of things, in the unrenewed soul. Duty and inclination are in conflict. Man's desires appetites and tendencies are in one direction, and his conscience is in the other. The sense of duty holds a whip over him. He yields to his sinful inclination, finds a momentary pleasure in so doing, and then feels the stings of the scorpion-lash. We see this operation in a very plain and striking manner, if we select an instance where the appetite is very strong, and the voice of conscience is very loud. Take, for example, that particular sin which most easily besets an individual. Every man has such a sin, and knows what it is, Let him call to mind the innumerable instances in which that particular temptation has assailed him, and he will be startled to discover how many thousands of times the sense of duty has put a restraint upon him. Though not in every single instance, yet in hundreds and hundreds of cases, the law of God has uttered the, "Thou shalt not," and endeavored to prevent the consummation of that sin. And what a wearisome experience is this. A continual forth-putting of an unlawful desire, and an almost incessant check upon it, from a law which is hated but which is feared. For such is the attitude of the natural heart toward the commandment. "The carnal mind is enmity against the law of God." The two are contrary to one another; so that when the heart goes out in its inclination, it is immediately hindered and opposed by the law. Sometimes the collision between them is terrible, and the soul becomes; an arena of tumultuous passions. The heart and will are intensely determined to do wrong, while the conscience is unyielding and uncompromising, and utters its denunciations, and thunders its warnings. And what a dreadful destiny awaits that soul, in whom this conflict and collision between the dictates of conscience, and the desires of the heart, is to be eternal! for whom, through all eternity, the holy law of God, which was ordained to life peace and joy, shall be found to be unto death and woe immeasurable!
II. In the second place, the sense of duty is a pain and sorrow to a sinful man, because it demands a perpetual effort from him.
No creature likes to tug, and to lift. Service must be easy, in order to be happy. If you lay upon the shoulders of a laborer a burden that strains his muscles almost to the point of rupture, you put him in physical pain. His physical structure was not intended to be subjected to such a stretch. His Creator designed that the burden should be proportioned to the power, in such a manner that work should be play. In the garden of Eden, physical labor was physical pleasure, because the powers were in healthy action, and the work assigned to them was not a burden. Before the fall, man was simply to dress and keep a garden; but after the fall, he was to dig up thorns and thistles, and eat his bread in the sweat of his face. This is a curse,—the curse of being compelled to toil, and lift, and put the muscle to such a tension that it aches. This is not the original and happy condition of the body, in which man was created. Look at the toiling millions of the human family, who like the poor ant "for one small grain, labor, and tug, and strive;" see them bending double, under the heavy weary load which they must carry until relieved by death; and tell me if this is the physical elysium, the earthly paradise, in which unfallen man was originally placed, and for which he was originally designed. No, the curse of labor, of perpetual effort, has fallen upon the body, as the curse of death has fallen upon the soul; and the uneasiness and unrest of the groaning and struggling body is a convincing proof of it. The whole physical nature of man groaneth and travaileth in pain together until now, waiting for the adoption, that is the redemption of the body from this penal necessity of perpetual strain and effort.
The same fact meets us when we pass from the physical to the moral nature of man, and becomes much more sad and impressive. By creation, it was a pleasure and a pastime for man to keep the law of God, to do spiritual work. As created, he was not compelled to summon his energies, and strain his will, and make a convulsive resolution to obey the commands of his Maker. Obedience was joy. Holy Adam knew nothing of effort in the path of duty. It was a smooth and broad pathway, fringed with flowers, and leading into the meadows of asphodel. It did not become the "straight and narrow" way, until sin had made obedience a toil, the sense of duty a restraint, and human life a race and a fight. By apostasy, the obligation to keep the Divine law perfectly, became repulsive. It was no longer easy for man to do right; and it has never been easy or spontaneous to him since. Hence, the attempt to follow the dictates of conscience always costs an unregenerate man an effort. He is compelled to make a resolution; and a resolution is the sign and signal of a difficult and unwelcome service. Take your own experience for an illustration. Did you ever, except as you were sweetly inclined and drawn by the renewing grace of God, attempt to discharge a duty, without discovering that you were averse to it, and that you must gather up your energies for the work, as the leaper strains upon the tendon of Achilles to make the mortal leap. And if you had not become weary, and given over the effort; if you had entered upon that sad but salutary passage in the religious experience which is delineated in the seventh chapter of Romans; if you had continued to struggle and strive to do your duty, until you grew faint and weak, and powerless, and cried out for a higher and mightier power to succor you; you would have known, as you do not yet, what a deadly opposition there is between the carnal mind and the law of God, and what a spasmodic effort it costs an unrenewed man even to attempt to discharge the innumerable obligations that rest upon him. Mankind would know more of this species of toil and labor, and of the cleaving curse involved in it, if they were under the same physical necessity in regard to it, that they lie under in respect to manual labor. A man must dig up the thorns and thistles, he must earn his bread in the sweat of his face, or he must die. Physical wants, hunger and thirst, set men to work physically, and keep them at it; and thus they well understand what it is to have a weary body, aching muscles, and a tired physical nature. But they are not under the same species of necessity, in respect to the wants and the work of the soul. A man may neglect these, and yet live a long and luxurious life upon the earth. He is not driven by the very force of circumstances, to labor with his heart and will, as he is to labor with his hands. And hence he knows little or nothing of a weary and heavy-laden soul; nothing of an aching heart and a tired will. He well knows how much strain and effort it costs to cut down forests, open roads, and reduce the wilderness to a fertile field; but he does not know how much toil and effort are involved, in the attempt to convert the human soul into the garden of the Lord.
Now in this demand for a perpetual effort which is made upon the natural man, by the sense of duty, we see that the law which was ordained to life is found to be unto death. The commandment, instead of being a pleasant friend and companion to the human soul, as it was in the beginning, has become a strict rigorous task-master. It lays out an uncongenial work for sinful man to do, and threatens him with punishment and woe if he does not do it. And yet the law is not a tyrant. It is holy, just, and good. This work which it lays out is righteous work, and ought to be done. The wicked disinclination and aversion of the sinner have compelled the law to assume this unwelcome and threatening attitude. That which is good was not made death to man by God's agency, and by a Divine arrangement, but by man's transgression.[2] Sin produces this misery in the human soul, through an instrument that is innocent, and in its own nature benevolent and kind. Apostasy, the rebellion and corruption of the human heart, has converted the law of God into an exacting task-master and an avenging magistrate. For the law says to every man what St. Paul says of the magistrate: "Rulers are not a terror to good works, but to the evil. Wilt thou, then, not be afraid of the power? Do that which is good, and thou shalt have praise of the same. For he is the minister of God to thee for good: but if thou do that which is evil, be afraid." If man were only conformed to the law; if the inclination of his heart were only in harmony with his sense of duty; the ten commandments would not be accompanied with any thunders or lightnings, and the discharge of duty would be as easy, spontaneous, and as much without effort, as the practice of sin now is.
Thus have we considered two particulars in which the Divine law, originally intended to render man happy, and intrinsically adapted to do so, now renders him miserable. The commandment which was ordained to life, he now finds to be unto death, because it places him under a continual restraint, and drives him to a perpetual effort. These two particulars, we need not say, are not all the modes in which sin has converted the moral law from a joy to a sorrow. We have not discussed the great subject of guilt and penalty. This violated law charges home the past disobedience and threatens an everlasting damnation, and thus fills the sinful soul with fears and forebodings. In this way, also, the law becomes a terrible organ and instrument of misery, and is found to be unto death. But the limits of this discourse compel us to stop the discussion here, and to deduce some practical lessons which are suggested by it.
1. In the first place, we are taught by the subject, as thus considered, that the mere sense of duty is not Christianity. If this is all that a man is possessed of, he is not prepared for the day of judgment, and the future life. For the sense of duty, alone and by itself, causes misery in a soul that has not performed its duty. The law worketh wrath, in a creature who has not obeyed the law. The man that doeth these things shall indeed live by them; but he who has not done them must die by them.
There have been, and still are, great mistakes made at this point. Men have supposed that an active conscience, and a lofty susceptibility towards right and wrong, will fit them to appear before God, and have, therefore, rejected Christ the Propitiation. They have substituted ethics for the gospel; natural religion for revealed. "I know," says Immanuel Kant, "of but two beautiful things; the starry heavens above my head, and the sense of duty within my heart."[3] But, is the sense of duty beautiful to apostate man? to a being who is not conformed to it? Does the holy law of God overarch him like the firmament, "tinged with a blue of heavenly dye, and starred with sparkling gold?" Nay, nay. If there be any beauty in the condemning law of God, for man the transgressor, it is the beauty of the lightnings. There is a splendor in them, but there is a terror also. Not until He who is the end of the law for righteousness has clothed me with His panoply, and shielded me from their glittering shafts in the clefts of the Rock, do I dare to look at them, as they leap from crag to crag, and shine from the east even unto the west.
We do not deny that the consciousness of responsibility is a lofty one, and are by no means insensible to the grand and swelling sentiments concerning the moral law, and human duty, to which this noble thinker gives utterance.[4] But we are certain that if the sense of duty had pressed upon him to the degree that it did upon St. Paul; had the commandment "come" to him with the convicting energy that it did to St. Augustine, and to Pascal; he too would have discovered that the law which was ordained to life is found to be unto death. So long as man stands at a distance from the moral law, he can admire its glory and its beauty; but when it comes close to him; when it comes home to him; when it becomes a discerner of the thoughts and intents of the heart; then its glory is swallowed up in its terror, and its beauty is lost in its truth. Then he who was alive without the law becomes slain by the law. Then this ethical admiration of the decalogue is exchanged for an evangelical trust in Jesus Christ.
