Faith is a theological expression; we are apt to forget that it has any other than a theological import; yet it is the commonest principle of man's daily life, called in that region prudence, enterprise, or some such name. It is in effect the principle on which alone any human superiority can be gained. Faith, in religion, is the same principle as faith in worldly matters, differing only in its object: it rises through successive stages. When, in reliance upon your promise, your child gives up the half-hour's idleness of to-day for the holiday of to-morrow, he lives by faith; a future supersedes the present pleasure. When he abstains from over-indulgence of the appetite, in reliance upon your word that the result will be pain and sickness, sacrificing the present pleasure for fear of future punishment, he acts on faith: I do not say that this is a high exercise of faith--it is a very low one--but it _is_ faith. Once more: the same motive of action may be carried on into manhood; in our own times two religious principles have been exemplified in the subjugation of a vice. The habit of intoxication has been broken by an appeal to the principle of combination, and the principle of belief. Men were taught to feel that they were not solitary stragglers against the vice; they were enrolled in a mighty army, identified in principles and interests. Here was the principle of the Church--association for reciprocated strength; they were thus taught the inevitable result of the indulgence of the vice. The missionaries of temperance went through the country contrasting the wretchedness and the degradation and the filth of drunkenness with the domestic comfort, and the health, and the regular employment of those who were masters of themselves. So far as men believed this, and gave up the tyranny of the present for the hope of the future--so far they lived by faith.
