But I have already dwelt so long upon this whole argument in a former lecture, that I will add no more in this place. If the facts which I have stated do not prove the miraculous agency of the Deity in past ages, I know not how it can be proved. But assuming this position to be established, and several inferences of importance will follow.

In the first place, this subject removes all philosophical presumption against a special revelation from heaven.

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.”

At the time when Mr. Hume wrote, and with his great skill in weaving together metaphysical subtilties, such an argument might deceive superficial minds; for then a miracle was supposed to be contrary to all experience. But geology has disclosed many new chapters in the world’s history, and shown the existence of miracles earlier than chronological dates. Even Mr. Hume would hardly deny that the creation of whole series of animals and plants was miraculous; and yet, in proof of that creation, we need not depend upon testimony; for we can read it with our own eyes upon the solid rocks. Such proof appeals directly to our common sense; nor can any ingenious quibble, concerning the nature of human testimony, weaken its influence in producing conviction.

And if God has wrought stupendous miracles of creation in order to people the world, who does not see that it is still more probable he would perform other miracles when they were needed to substantiate a revelation of his will to those moral and accountable beings, who needed its special teachings to make them acquainted with their God, their duty, and their destiny?

Finally. The subject removes all presumption against the exercise of a special and miraculous providence in the divine government of the world.

In all ages of the world, philosophers, and even many theologians, have been strenuous opposers of special and miraculous providence. If they have admitted, as most of the latter class have done, that some miracles were performed in ancient times, they have strenuously maintained that the doctrine of special providence in these days is absurd, and that God cannot, without a miracle, bestow any special favors upon the virtuous in answer to their prayers, or inflict any special punishments upon the wicked; and that it is fanaticism to expect any other retributions than such as the ordinary and unmodified course of nature brings along with it.

The unvarying constancy of nature, in consequence of being governed by fixed laws, is the grand argument which they adduce in opposition to any supposed special providence. Since the fathers fell asleep, say they, all things continue as they were from the beginning. God has subjected the world to the government of laws, and he will not interfere with, counteract, set aside, or give a supernatural force to those laws, to meet particular exigencies. For the adjustment of all apparent inequalities of good and evil, suffering and enjoyment here, we must wait for the disclosure of eternity, when strict retributive Justice will hold her even scales. When natural evils come upon us, therefore, it is idle to expect their removal, except so far as they may be mitigated or overcome by natural means; and hence it is useless to pray for their removal, or to expect God will deliver us from them in any other way. When the heavens over us become brass, and the earth under our feet iron, and the rain of our land is powder and dust, and want, and famine, as the consequence, stalk forth among the inhabitants, of what use to pray to God for rain, since to give it would require a miracle, and the age of miracles has passed? When the pestilence is scouring through the land, and our neighbors and nearest friends are within its grasp, and we may next become its victims,—nay, when we, too, are on the borders of the grave,—why should we expect relief by prayer, since sickness is the result of natural causes, and God will not interpose to save us from the effects of natural evils, because that would be contrary to a fixed rule of his government? When dangers cluster around the good man in the discharge of trying duties, it would be enthusiasm in him to expect any special protection against his enemies, though he pray ever so fervently, and trust in divine deliverance with ever so much confidence. He must look to another world for his reward, if called to suffer here. Nor has the daringly wicked man any reason to fear that God will punish his violations of the divine law by any unusual display of his power; not in any way, indeed, but by the evils which naturally flow from a wicked life. In short, it will be useless to pray for any blessing that requires the least interference with natural laws, or for the removal of any evil which depends upon those laws. And since our minds are controlled as much by laws as the functions of our bodies, we are not to expect any blessings in our souls, which require the least infringement of intellectual laws. In fine, the effect of prayer is limited almost entirely to its influence upon our own hearts, in preparing them to receive with a proper spirit natural blessings, and to bear aright natural evils; to stimulate us to use with more diligence the means of avoiding or removing the latter, and securing the former.
