So much for the senses with which we are endowed, and the information which the mind receives through their respective channels. They teach us all that we know concerning the qualities of matter, and they subserve many of our enjoyments--they are essential to our comfort, our activity, our usefulness; but we gain through their medium no abstract truths, no determinate principles. These are elaborated in the mind itself by its own self-analysis; but, then, they do not teach us our own position as it respects time and eternity. The wisest of the heathens of Greece or Rome lived in doubt, entangled in the mazes of a vain system of philosophy; and though they might believe in a god, or in gods, deducing their arguments as to the existence of an all-powerful Being from the works of nature, and from that internal conviction which seems common to the human race--they knew nothing of His attributes, of his laws, of his requirements, of man's fallen nature, of the intrinsic sinfulness of the heart, of the means of grace, of a hope of glory. They could write noble poems, deep philosophic treatises, histories of empires, narratives of events, details of characters, descriptions of works of art; they could carve statues of matchless perfection, and build temples of surpassing splendour. They displayed an intellectual pre-eminence, which still sheds a lustre over the civilized world. Who by searching can find out God? Unless God graciously reveals himself to us, a true knowledge of him in our fallen state is impossible; the capabilities of our minds are, after all, but limited; and though, through reflection on the evidences of our senses, we may come to the conclusion that there is an omnipotent Power, we remain in ignorance as to what that Power is, and as to our relationship thereunto. Hence, then, the necessity of information beyond what the mind can gain through the senses, or by its own reflex operations; we are conscious of our position as respects the lower animals, and we have natural longings after and hopes of immortality; the soul whispers to itself, _Non omnis moriar_, I shall not all die; but here, were it not for revelation--a revelation from God, we should be left in darkness.
