The mass of good, well-meaning Christians are not yet advanced enough to guess at the change which a perfect fidelity to Christ's spirit and precepts would produce in them. And the majority of people who call themselves well, because they are not, at present, upon any particular doctor's list, are not within sight of what perfect health would be. That fullness of life, that vigorous tone, and that elastic cheerfulness, which make the mere fact of existence a luxury, that suppleness which carries one like a well-built boat over every wave of unfavorable chance,--these are attributes of the perfect health seldom enjoyed. We see them in young children, in animals, and now and then, but rarely, in some adult human being, who has preserved intact the religion of the body through all opposing influences. Perfect health supposes not a state of mere quiescence, but of positive enjoyment in living. See that little fellow, as his nurse turns him out in the morning, fresh from his bath, his hair newly curled, and his cheeks polished like apples. Every step is a spring or a dance; he runs, he laughs, he shouts, his face breaks into a thousand dimpling smiles at a word. His breakfast of plain bread and milk is swallowed with an eager and incredible delight,--it is so good that he stops to laugh or thump the table now and then in expression of his ecstasy. All day long he runs and frisks and plays; and when at night the little head seeks the pillow, down go the eye-curtains, and sleep comes without a dream. In the morning his first note is a laugh and a crow, as he sits up in his crib and tries to pull papa's eyes open with his fat fingers. He is an embodied joy,--he is sunshine and music and laughter for all the house. With what a magnificent generosity does the Author of life endow a little mortal pilgrim in giving him at the outset of his career such a body as this! How miserable it is to look forward twenty years, when the same child, now grown a man, wakes in the morning with a dull, heavy head, the consequence of smoking and studying till twelve or one the night before; when he rises languidly to a late breakfast, and turns from this and tries that,--wants a deviled bone, or a cutlet with Worcestershire sauce, to make eating possible; and then, with slow and plodding step, finds his way to his office and his books. Verily the shades of the prison-house gather round the growing boy; for, surely, no one will deny that life often begins with health little less perfect than that of the angels.
