Conscience is Judge and Lawgiver.—​But the will by no means carries on the government of the kingdom of Mansoul single-handed. True, the will wields the executive power; it is only by willing we are enabled to do; but there is a higher power behind, whose mandate the will does no more than express. Conscience sits supreme in the inner chamber. Conscience is the lawgiver, and utters the ‘Thou shalt’ and the ‘Thou shalt not’ whereon the will takes action; the judge, too, before whom the offending soul is summoned; and from the ‘Thou art the man’ of conscience, there is no appeal.

I am, I ought, I can, I will.’—‘I am, I ought, I can, I will’—these are the steps of that ladder of St Augustine, whereby we

“rise on stepping-stones

Of our dead selves to higher things.”

‘I am’—we have the power of knowing ourselves. ‘I ought’—we have within us a moral judge, to whom we feel ourselves subject, and who points out and requires of us our duty. ‘I can’—we are conscious of power to do that which we perceive we ought to do. ‘I will’—we determine to exercise that power with a volition which is in itself a step in the execution of that which we will. Here is a beautiful and perfect chain, and the wonder is that, so exquisitely constituted as he is for right-doing, error should be even possible to man. But of the sorrowful mysteries of sin and temptation it is not my place to speak here; you will see that it is because of the possibilities of ruin and loss which lie about every human life that I am pressing upon parents the duty of saving their children by the means put into their hands. Perhaps it is not too much to say, that ninety-nine out of a hundred lost lives lie at the door of parents who took no pains to deliver their children from sloth, from sensual appetites, from wilfulness, no pains to fortify them with the habits of a good life.

Inertness of Parents not supplemented by Divine Grace.—​We live in a redeemed world, and infinite grace and help from above attend every rightly directed effort in the training of the children; but I do not see much ground for hoping that divine grace will step in as a substitute for any and every power we choose to leave unused or misdirected. In the physical world, we do not expect miracles to make up for our neglect of the use of means; the rickety body, the misshapen limb, for which the child has to thank his parents, remain with him through life, however much else he may have to thank God for; and a feeble will, bad habits, an uninstructed conscience, stick by many a Christian man through his life, because his parents failed in their duty to him, and he has not had force enough in himself to supply their omission.

Conscience not an Infallible Guide.—​In this matter of conscience, for instance, the laissez-faire habit of his parents is the cause of real wrong and injury to many a child. The parents are thankful to believe that their child is born with a conscience; they hope his conduct may be ruled thereby: and the rest they leave; the child and his conscience may settle it between them. Now this is to suppose, either that a fully-informed conscience is born into an infant body, or that it grows, like the hair and the limbs, with the growth of the body, and is not subject to conditions of spiritual progress proper to itself. In other words, it is to suppose that conscience is an infallible guide, a delusion people cling to in spite of common sense and of everyday experience of the wrong-headed things men do from conscientious motives. The vagaries of the uninstructed conscience are so familiar as to have given rise to popular proverbs: ‘Honour among thieves,’ ‘To strain out the gnat and swallow the camel,’ point to cases of misguided conscience; while ‘The wish is father to the thought,’ ‘None is so blind as he who won’t see,’ point to the still more common cases, in which a man knowingly tricks his conscience into acquiescence.

But a real Power.—​Then, if conscience be not an infallible guide—if it pass blindfold by heinous offences, and come down heavily upon some mere quibble, tithing mint, rue, and all manner of herbs, and neglecting the weightier matters of the law—if conscience be liable to be bamboozled, persuaded into calling evil good and good evil, when Desire is the special pleader before the bar, where is its use, this broken reed? Is this stern lawgiver of the breast no more, after all, than a fiction of the brain? Is your conscience no more than what you happen to think about your own actions and those of other people? On the contrary, these aberrations of conscience are perhaps the strongest proof that it exists as a real power. As Adam Smith has well said, “The supreme authority of conscience is felt and tacitly acknowledged by the worst, no less than by the best, of men; for even they who have thrown off all hypocrisy with the world, are at pains to conceal their real character from their own eyes.”

That Spiritual Sense whereby we know Good and Evil.—​What conscience is, how far it lies in the feelings, how far in the reason, how far it is independent of both, are obscure questions which it is not necessary for practical purposes to settle; but this much is evident—that conscience is as essential a part of human nature as are the affections and the reason, and that conscience is that spiritual sense whereby we have knowledge of good and evil. The six-months-old child who cannot yet speak exhibits the workings of conscience; a reproving look will make him drop his eyes and hide his face. But, observe, the mother may thus cover him with confusion by way of an experiment when the child is all sweetness, and the poor little untutored conscience rises all the same, and condemns him on the word of another.

Facts like this afford a glimpse of the appalling responsibility that lies upon parents. The child comes into the world with a moral faculty, a delicate organ whereby he discerns the flavour of good and evil, and at the same time has a perception of delight in the good—in himself or others,—of loathing and abhorrence of the evil. But, poor little child, he is like a navigator who does not know how to box his compass. He is born to love the good, and to hate the evil, but he has no real knowledge of what is good and what is evil; what intuitions he has, he puts no faith in, but yields himself in simplicity to the steering of others. The wonder that Almighty God can endure so far to leave the very making of an immortal being in the hands of human parents is only matched by the wonder that human parents can accept this divine trust with hardly a thought of its significance.
