"The heart of the sons of men is full of evil, and madness is in their heart while they live."-Eccl. ix. 3.

THE Bible often ascribes to unconverted men one common heart or disposition. It always makes two classes, and only two, of our race -- saints and sinners; the one class converted from their sin and become God's real friends; the other remaining His unconverted enemies. According to the Bible, therefore, the heart, in all unrenewed men, is the same in its general character. In the days of Noah, God testified "that the wickedness of man was great on the earth, and that every imagination of the thought of his heart was only evil continually." Observe, He speaks of the thought of their heart, as if they had one common heart -- all alike in moral character. So by Paul, God testifies that "the carnal mind is enmity against God," testifying thus, not of one man, or of a few men, but of all men of carnal mind. So in our text, the phraseology is expressive: "the heart of the sons of men is full of evil" -- as if the sons of men had but one heart -- all in common -- and this one heart were "full of evil." You will notice this affirmation is not made of one or two men, nor of some men, merely; but "of the sons of men:" as if of them all.

1. But what is intends by affirming that "madness is in their heart while they live?"

This is not the madness of anger, but of insanity. True, sometimes people are mad with anger; but this is not the sense of our text. The Bible, as well as customary speech, employs this term, "madness" -- to express insanity. This we understand to be its sense here.

Insanity is of two kinds. One of the head; the other of the heart. In the former, the intellect is disordered, latter, the will and voluntary powers. Intellectual insanity destroys moral agency. The man, intellectually insane, is not, for the time, a moral agent; moral responsibility is suspended because he can not know his duty, and can not choose responsibly as to doing or not doing it. True, when a man makes himself temporarily insane, as by drunkenness, the courts are obliged to hold him responsible for his acts committed in that state; but the guilt really attaches to the voluntary act which creates the insanity. A man who gets intoxicated by intelligently drinking what he knows is intoxicating, must be held responsible for his acts during the pursuing intoxication. The reason of this is, that he can foresee the danger, and can easily avoid it.

The general law is that, while the intellect retains its usual power, so long moral obligation remains unimpaired.

Moral insanity, on the other hand, is will-madness. The man retains his intellectual powers unimpaired. but he sets his heart fully to He refuses to yield to the demands of his conscience. He practically discards the obligations of moral responsibility. He has the powers of free moral agency, but persistently abuses them. He has a reason which affirms obligation, but he refuses obedience to its affirmations.

In this form of insanity, the reason remains unimpaired; but the heart deliberately disobeys. The insanity spoken of in the text is moral. that of the heart. By the heart here, is meant the will -- the voluntary power. While the man is intellectually sane, he yet acts as if he were intellectually insane.

It is important to point out some of the manifestations of this state of mind. Since the Bible affirms it to be a fact that sinners are mad in heart, we may naturally expect to see some manifestations of it. It is often striking to see how perfectly the Bible daguerreotypes human character; has it done so in reference to this point? Let us see.

Who are the morally insane?

Those who, not being intellectually insane, yet ACT as if they were.

For example, those who are intellectually insane, treat fiction as if it were reality, and reality as if it were fiction. They act as if truth were not truth, and as if falsehood were truth. Every man knows that insane people actually follow the wild dreams of their own fancy, as if they were the most stem reality, and can scarcely be made to feel the force of anything truly real.

So men, in their sins, treat the realities of the spiritual world as if they were not real, but follow the most empty phantoms of this world, as if they were stern realities.

They also act as if self were of supreme importance, and everything else of relatively no importance. Suppose you were to see a man acting this out in common life. He goes round, day after day, assuming that he is the Supreme God, and practically insisting that everybody ought to have a supreme regard to his rights, and comparatively little or no regard for other people's rights. Now, if you were to see a man saying this and acting it out, would you not account him either a blasphemer or insane?

Observe, now, the wonderful fact, that while wicked men talk so sensibly as to show that they know better, yet they act as if all this were true -- as if they supposed their own self-interest to be more important than everything else in the universe, and that God's interests, and rights even, are nothing in comparison. Practically, every sinner does this.

It is an essential element in all sin. Selfish men never regard the rights of anybody else, unless they are in some way linked with their own.

If wicked men really believed their own rights and interests to be supreme in the universe, it would prove them intellectually insane, and we should hasten to shut them up in the nearest mad- house; but when they show that they know better, yet act on this groundless assumption, in the face of their better knowledge, we say, with the Bible, that "madness is in their hearts while they live."

Again, see this madness manifested in his relative estimate of time and of eternity. His whole life declares that, in his view, it is by far more important to secure the good of time than the good of eternity. Yet, if a man should reason thus should, argue to prove it, and should soberly assert it -- you would know him to be insane, and would help him to the mad-house. But, suppose he does not say this -- dares not say it -- knows it is not true; yet constantly acts it out, and lives on the assumption of its truth, what then? Simply this -- he is morally mad. Madness is in his heart.

Now precisely this is the practice of every one of you who is living in sin. You give the preference to time over eternity, You practically say -- O give me the joys of time: why should I trouble myself yet about the trivial matters of eternity?

In the same spirit you assume that the body is more than the soul. But if a man were to affirm this and go round trying to prove it, you would know him to be insane. O, if he were a friend of yours, how your heart would break for his sad misfortune reason lost! But if he knows better, yet practically lives as if it were even so, you only say, he is morally insane -- that is all!

Suppose you see a man destroying his own property, not by accident or mistake, but deliberately; injuring his own health, also, as if he had no care for his own interests; you might bring his case before a judge and sue out a commission of lunacy against him; under which the man's goods should be taken out of his own control, and he be no longer suffered to squander them. Yet, in spiritual things, wicked men will deliberately act against their own dearest interests; having a price put into their hands to get wisdom, they will not use it; having the treasures of heaven placed within their reach, they do not try to secure them; with an infinite wealth of blessedness proffered for the mere acceptance, they will not take it as a gift. Indeed! How plain it is that, if men were to act in temporal things as they do in spiritual, they would be pronounced by everybody insane. Any man would take his oath of it. They would say -- Only see; the man acts against his own interests in everything! Who can deny that he is insane? Certainly sane men never do this!

But, in moral questions, wicked men seem to take the utmost pains to subvert their own interests, and make themselves insolvent forever! O, how they beggar their souls, when they might have the riches of heaven.

Again, they endeavor to realize manifest impossibilities. For example, they try to make themselves happy in their sins and their selfishness, Yet they know they can not do it. Ask them, and they will admit the thing is utterly impossible; and yet, despite of this conviction, they keep up the effort perpetually to try -- as if they expected by and by to realize a manifest impossibility. Now, in moral things, it may not strike you as specially strange, for it is exceedingly common; but suppose, in matters of the world, you were to see a man doing the same sort of thing, what would you think of him? For example, you see him working hard to build a very long ladder, and you ask him what for. He says, "I am going to scale the moon." You see him ex. pending his labor and his money, with the toil of a life, to get up a mammoth ladder with which to scale the moon I Would you not say -- He is certainly insane? For unless he were really insane, he would know it to be an utter impossibility. But, in spiritual things, men are all the time trying to realize a result at least equally impossible -- that of being happy in sin -- happy with a mutiny among their own constitutional powers, the heart at war against reason and conscience. The pursuit of happiness in sin is as if a man were seeking to bless himself by mangling his own flesh, digging out his own eyes, knocking in his teeth. Yet men as really know that they can not obtain happiness in sin and selfishness, as they know they can not ensure health and comfort by mutilating their own flesh and tearing their own nerves in sunder. Doing thus madly what they know will always defeat and never ensure real happiness, they show themselves to be morally insane.

Another manifestation of intellectual insanity is loss of confidence in one's best friends. Often this is one of the first and most painful evidences of insanity -- the poor man will have it that his dearest friends are set to ruin him. By no amount of evidence can he be persuaded to think they are his real friends.
