But, the man converted, the work is not done. These sinners exceedingly are not only sinful, but diseased; morbid conditions of brain have been set up, and every one of them needs individual treatment, like any other sick man, for disease slow of cure. For a month, three months, six months, it will not do to let one of them alone. Curative _treatment_ is an absolute condition of success, and here is where human co-operation is invited in what is primarily and ultimately the work of God. There are diseased places in the brain, where ill thoughts have of old run their course; and these sore places must have time, blessed time, wherein to heal. That is to say, all traffic in the old thoughts must be absolutely stopped, at whatever cost. Think of the Army of Vigilance which must be ever on the alert to turn away the eyes of the patients from beholding evil; for, a single suggestion, of drink, of uncleanness, and, _presto_, the old thoughts run riot, and the work of healing must be begun anew. And, how to keep out the old, but by administering the thoughts of the new life watchfully, one by one, as they are needed, and can be taken; offering them with engaging freshness, with comforting fitness, until at last the period of anxious nursing is over, the habits of the good life are set up, and the patient is able to stand on his own feet and labour for his own meat. This is no work to be undertaken wholesale. The spiritual care of a multitude diseased, even physically diseased, of sin, is no light thing. And if it be not undertaken systematically, and carried out efficiently, the whole scheme must of necessity fall through. Who is sufficient for these things? No one, perhaps; but a following of a great corps of nurses trained to minister to minds diseased, and with the experience and the method belonging to a professional calling, is surely, a fitting qualification for the Herculean task. THE EASE OF DISCIPLINE.
