We look with intense interest to the young men of London. With pain, such as we cannot describe, we regard the gay, the dissolute, the intemperate--those who drown the higher faculties of the soul in sensual indulgence, who degrade their mental, moral, and spiritual nature, and, forgetting their relationship to angels, sink to the level of the brutes that perish. With pleasure, however, equally indescribable, we turn to the steady, the sober, the virtuous, the enlightened--those who labor after mental improvement, and especially those who seek spiritual excellence, who ask and practically answer the question, "While I am attending to the intellectual culture of the mind, ought I not to prepare for that eternity to which I am hastening, where moral and spiritual character will be all in all?" and who, repairing to the word of God, the source of all religious wisdom, have become the subjects of a discipline, which adorns the intellect with the beauties of sanctity, and prepares the soul for the vision and worship of heaven. Of such, London may well say with the mother of the Gracchi, but in a far more important sense, "These are my jewels." Let it be the endeavor, as it is the duty of London citizens, to aid all wise schemes for its physical and intellectual amelioration, but especially such as relate to morals and religion. With a clear eye, a loving heart, a steady hand, and a determined will, each must apply himself to pulling down the evil, and building up the good. The moral health of a city should be the care of all its members. The most precious object amidst the multitude of precious things in the chief city of England is the citizen himself. Man, out of whose intellect, energy, and power, all the rest has grown--man, in whose capacities are found the germs of a greatness, the cultivation of which will a thousand times repay the toil it involves. The noblest of enterprises, be it remembered, is to be found, not in commercial speculation, or political reform, or even literary and scientific knowledge, but in the promotion of Christ's holy and saving religion, and in the recovery and purification of the soul, through faith in him, and its preparation for other realms of being in the infinite Hereafter. The enduring magnificence of such labor and its results exceeds all the doings of earthly ambition, even as the mighty Alps and Andes surpass the houses of ice and snow which children in their sports build up, and which are melting away before that sun in whose rays they glitter.
