The benevolent activities called forth in our late dreadful war illustrate the blessed influence on character and happiness in having a noble object for which to labor and suffer. In illustration of this, may be mentioned the experience of one of the noble women who, in a sickly climate and fervid season, devoted herself to the ministries of a military hospital. Separated from an adored husband, deprived of wonted comforts and luxuries, and toiling in humble and unwonted labors, she yet recalls this as one of the happiest periods of her life. And it was not the mere exercise of benevolence and piety in ministering, comfort and relieving suffering. It was, still more, the elevated enjoyment which only an enlarged and cultivated mind can attain, in the inspirations of grand and far-reaching results purchased by such sacrifice and suffering. It was in aiding to save her well-loved country from impending ruin, and to preserve to coming generations the blessings of true liberty and self-government, that toils and suffering became triumphant joys. Every Christian woman who "walks by faith and not by sight," who looks forward to the results of self-sacrificing labor for the ignorant and sinful as they will enlarge and expand through everlasting ages, may rise to the same elevated sphere of experience and happiness. On the contrary, the more highly cultivated the mind devoted to mere selfish enjoyment, the more are the sources of true happiness closed and the soul left to helpless emptiness and unrest. The indications of a diseased mind, owing to the want of the proper exercise of its powers, are apathy, discontent, a restless longing for excitement, a craving for unattainable good, a diseased and morbid action of the imagination, dissatisfaction with the world, and factitious interest in trifles which the mind feels to be unworthy of its powers. Such minds sometimes seek alleviation in exciting amusements; others resort to the grosser enjoyments of sense. Oppressed with the extremes of languor, or over-excitement, or apathy, the body fails under the wearing process, and adds new causes of suffering to the mind. Such, the compassionate Saviour calls to his service, in the appropriate terms, "Come unto me, all ye that labor and are heavy laden, and I will give you rest. Take my yoke upon you, and learn of me," "and ye shall find rest unto your souls." XXI. THE CARE OF INFANTS.
