The view just suggested may lead us to some just conceptions of what is necessary to be done in attempting to explain the prophecies. Suppose, then, _first_, that there had been, say in the dark ages, some predictions that claimed to be of divine origin, of the invention of the art of printing and of the magnetic telegraph. The proper business of an interpreter, if he regarded this as a divine communication, would have consisted in four things: (a) to explain, as well as he could, the fair meaning of the symbols employed, and the language used; (b) to admit the _fact_ referred to, and implied in the fair interpretation of the language employed, of the rapid spread of intelligence in that future period, though he could not explain _how_ it was to be done; (c) in the meantime it would be a perfectly legitimate object for him to inquire whether there were any events occurring in the world, or whether there had been any, to which these symbols were applicable, or which would meet all the circumstances involved in them; (d) if there were, then his duty would be ended; if there were not, then the symbols, with such explanation as could be furnished of their meaning, should be handed on to future times, _to be_ applied when the predicted events should actually occur. Suppose, then, _secondly_, the case of the predictions respecting the Messiah, scattered along through many books, and given in various forms, and by various symbols. The proper business of an interpreter would have been, as in the other case, (a) to explain the fair meaning of the language used, and to bring together all the circumstances in one connected whole, that a distinct conception of the predicted Messiah might be before the mind; (b) to admit the _facts_ referred to, and thus predicted, however incomprehensible and apparently contradictory they might appear to be; (c) to inquire whether anyone had appeared who combined within himself all the characteristics of the description; and (d) if no one had thus appeared, to send on the prophecies, with such explanations of words and symbols as could be ascertained to be correct, to future times, to have their full meaning developed when the object of all the predictions should be accomplished, and the Messiah should appear. Then the meaning of all would be plain; and then the argument from prophecy would be complete. This is obviously now the proper state of the mind in regard to the predictions in the Bible, and these are the principles which should be applied in examining the book of Revelation.
