As with the body, so with the spirit. Habitual inaction enfeebles the faculties, and renders their occasional operation inefficient and fruitless. On the contrary, by habitual exercise one becomes capable of performing with ease what were otherwise laborious and difficult, if not quite impossible. Thus the young, accustomed to resist their evil passions, will afterward keep them in due control without any very strenuous struggle; and the seeds of a pure morality, sown in early life, will strike their roots deep into the soil, and spring up in perpetual blossom and fruitage. The person is thenceforth virtuous, not without effort, but certainly with less effort than if he had never accustomed himself to virtue. The habit of virtue has made virtue amiable, and her service becomes a labor of love, her yoke easy and her burden light. In speaking thus of the power of habit, which has been called "a second nature," I would not exclude from the process of education the agency of divine grace, nor lose sight of it as a necessary factor to the best results. Divine grace, indeed, has much to do with the formation of the habit, and must co-operate with every agency employed in the work. Without divine grace, there is nothing wise, nothing strong, nothing holy; and after all the efforts of parents, pastors, teachers--however great or however small the measure of success attained--we lift our hands to Heaven and sing:-- "Thou all our works in us hast wrought, Our good is all divine; The praise of every virtuous thought And righteous word is thine. From thee, through Jesus, we receive The power on thee to call; In whom we are, and move, and live-- Our God, our all in all." An infidel objected to sending his little daughter to the Sunday school, "because," said he, "they learn things there which they never forget." The infidel was a philosopher. Knowledge is indestructible. The fact or the principle once acquired is never lost. The soul's past thoughts, feelings, impressions, and operations, are its inalienable property. They are engraven upon an imperishable tablet, and no power can efface the record. Though some parts of our experience may be but dimly and vaguely remembered, and much that we have learned may seem to be irrevocably forgotten, yet the mind is in possession of a law which, when brought into action, will completely restore the entire train of its former phenomena. They are not dead, but sleeping; and we know not what event at some future day may be the trump of their resurrection. The seed that lies buried in the earth through the long and dreary winter will germinate in spring-time and fructify in summer. Therefore let us not be weary in well-doing, for in due season we shall reap if we faint not.
