Moral helplessness: how induced.
I. THE EXTENT TO WHICH IT MAY GO. The metaphors employed are intended to illustrate the difficulty of getting rid of that which has become a part of one's self, or which has become natural to one. It is evident that superficial means would never produce the effect supposed, because that which seems to be superficial has really its root in the nature, and would be reproduced similarly in place of that which was removed. The doctrine is that there are certain evils into which men fall which may appear to be external, matters of custom and observance, but which have really their origin in the depravity of the heart. Any merely external reform, like that of Josiah, would fail to effect a permanent change, because the source of the errors and transgressions which were corrected was deeper than the remedy could reach. And this is the case with the sins of men. To cease to do evil we have not only to stay the hand but to purify the heart. To cease to do evil we must cease to think it, to feel it, and to conceive it. So helpless is the sinner when he stands face to face with the problem of reformation. Effort after effort is made and fails. It is bound to fail because the source of the wrong-doing has net been rectified. To change himself—who is capable of this feat?
II. CAUSES OF IT, REAL AND UNREAL. Excuses readily suggest themselves to the sinner who would avoid the humiliation of repentance. He may ask the question, as if it were a mystery, "Wherefore come these things upon me?" Or, ignoring the witness of conscience, he may attribute his weakness to circumstances and external influences. This is the error which the prophet refutes. With great skill he shows the terrible power of habit: how men continue to do that which they have been doing simply because they have been doing it. The feet acquire a fatal facility in transgression, and the, hands a skill in working evil. They almost act automatically when things forbidden are suggested. But when the commandments of God are concerned they are unfamiliar with the duties enjoined, and the will is not resolute enough to persevere in them.
III. ITS GREAT REMEDY. Seeing that in himself the sinner is without strength, it would appear at first as if he could only despair. But this is not the teaching of the prophet. He has already counseled vigorous effort, and implied that a commencement and continuance in well-doing were possible. But the change could only begin at a spiritual point, viz. repentance. And this, as Scripture abundantly shows, though within the power of every one, is a supernatural grace. A true sorrow for sin may be induced in answer to prayer, by the study of Scripture, and the contemplation of Christ; but it is always the work of the Holy Spirit. When that grace, however, has once been attained, it is open to the sinner to reverse the process by which he has been enslaved. After conversion evil habit will assert itself, and can only be met by constant dependence upon Divine grace and constant effort after holiness. The good habit formed by repeated and regular actions according to the Law of God is the best antidote to the evil one.—M.
