1. It works repentance. By repentance is meant, in Scripture, change of life, alteration of habits, renewal of heart. This is the aim and meaning of all sorrow. The consequences of sin are meant to wean from sin. The penalty annexed to it is in the first instance, corrective, not penal. Fire burns the child, to teach it one of the truths of this universe--the property of fire to burn. The first time it cuts its hand with a sharp knife, it has gained a lesson which it never will forget. Now, in the case of pain, this experience is seldom, if ever, in vain. There is little chance of a child forgetting that fire will burn, and that sharp steel will cut; but the moral lessons contained in the penalties annexed to wrong-doing are just as truly intended, though they are by no means so unerring in enforcing their application. The fever in the veins and the headache which succeed intoxication, are meant to warn against excess. On the first occasion they are simply corrective; in every succeeding one they assume more and more a penal character in proportion as the conscience carries with them the sense of ill desert. Sorrow then, has done its work when it deters from evil; in other words when it works repentance. In the sorrow of the world, the obliquity of the heart towards evil is not cured; it seems as if nothing cured it: heartache and trials come in vain; the history of life at last is what it was at first. The man is found erring where he erred before. The same course, begun with the certainty of the same desperate end which has taken place so often before. They have reaped the whirlwind, but they will again sow the wind. Hence I believe, that life-giving sorrow is less remorse for that which is irreparable, than anxiety to save that which remains. The sorrow that ends in death hangs in funeral weeds over the sepulchres of the past. Yet the present does not become more wise. Not one resolution is made more firm, nor one habit more holy. Grief is all. Whereas sorrow avails _only_ when the past is converted into experience, and from failure lessons are learned which never are to be forgotten. 2. Permanence of alteration; for after all, a steady reformation is a more decisive test of the value of mourning than depth of grief. The susceptibility of emotion varies with individuals. Some men feel intensely, others suffer less keenly; but this is constitutional, belonging to nervous temperament, rather than to moral character. _This_ is the characteristic of the divine sorrow, that it is a repentance "not repented of;" no transient, short-lived resolutions, but sustained resolve.
