If we can prove that the Deity has often so interfered with the course of nature as to introduce new species, nay, whole races of animals and plants upon the globe,--if, in a comparatively recent period, he has created a moral and immortal being, endowed with all the powers of a free and an accountable agent,--it would surely be no more wonderful if he should communicate to that being his will by a written revelation. Indeed, the benevolence of the Deity, as we learn it from nature, would create a presumption that such a revelation would be given, if it appear, as we know it does, that no sufficient knowledge is inherent in his nature to guide him in the path of duty; since such a revelation would be no greater miracle than to people the world, originally destitute of life, and then to repeople it again and again, with so vast a variety of organic natures. Philosophy has sometimes been disinclined to admit the claims of revelation, because it implies a supernatural agency of the Deity; and, until recently, revelation seemed to be a solitary example of special interference on the part of Jehovah. But geology adds other examples, long anterior to revelation--examples registered, like the laws of Sinai, on tables of stone. And the admission of the geological evidence of special interference with the regular sequence of nature's operations ought to predispose the mind for listening to the appropriate proofs of a moral communication to ignorant and erring man. _In the second place, the subject shows us how groundless is the famous objection to the miracles recorded in Scripture, founded on the position that they are contrary to experience._ "It is," says Mr. Hume, "a maxim worthy of our attention, that no testimony is sufficient to establish a miracle, unless the testimony be of such a kind, that its falsehood would be more miraculous than the fact which it endeavors to establish." Hence he asserts, that "the evidence of testimony, when applied to a miracle, carries falsehood on the very face of it, and is more properly a subject of derision than of argument," and that "whoever believes the Christian religion is conscious of a continued miracle in his own person, which subverts all the principles of his understanding, and gives him a determination to believe what is most contrary to custom and experience."
