An omnipresent, omniscient, and almighty Being, presiding over the affairs of His own world, as the author, upholder, and governor of all things, may well be conceived to have infinite resources at His command,—such as we can never fully estimate,—by which he can give effect to prayer in ways that may be to us inscrutable. But our ignorance of the mode is no reason for doubting the reality of His interposition in answer to prayer; and even if we were unable to decide on the comparative merits of the various explanations of it which have been proposed, the mere fact that there are several solutions, at once conceivable and credible, any one of which may be sufficient, as a hypothetical explanation, to neutralize every adverse presumption, should be held tantamount to a proof that no valid or conclusive objection can be urged against it. Dr. Chalmers has frequently illustrated the legitimate and important uses of "hypothetical solutions" in Theology; and has conclusively shown that even where they leave us at a loss to determine which of various methods of solving a difficulty is the truest or the best, they yet serve a great purpose, if they merely neutralize an objection, by showing that the difficulty in question might be satisfactorily accounted for, were our knowledge more extensive or more precise.[210] Now, with regard to "the efficacy of prayer," there are four distinct solutions, or rather four different methods of disposing of the difficulty, any one of which is sufficient to vindicate the claims of the doctrine on our faith. We shall not discuss the respective merits of these various solutions in detail, but shall merely state them, with the view of showing that there are several methods of accounting for "the efficacy of prayer" in perfect consistency with the established order of Nature.

The first is the theory of those who hold that there is the same relation between prayer and the answer to prayer as between cause and effect in any other sequence of Nature. Prayer is supposed to be the cause, and the answer the effect; and this by an invariable law, established in the original constitution, and manifested in the uniform course, of the world. To this solution Dr. Chalmers seems to refer when he says, that "the doctrine of the efficacy of prayer but introduces a new sequence to the notice of the mind," that "it may add another law of Nature to those which have been formerly observed," and that "the general truth may be preserved, that the same result always follows in the same circumstances, although it should be discovered that prayer is one of those influential circumstances by which the result is liable to be modified."[211] Now, if it be meant merely to affirm that, in the administration of His providential government, God has respect to the prayers of men as a consideration which affects their relation to Him and His treatment of them, and that this rule is as invariable as any other law of Nature, the principle that is involved in this solution may be admitted as sound and valid; but if it be further meant, that prayer and the answer to prayer are in all respects similar to any other instance of cause and effect, it must be remembered that the answer is not the effect of the prayer, at least directly and immediately, but the effect of the Divine will; and then the question suggested by Dr. M'Cosh—whether causality can properly be ascribed to our prayers with reference to the Divine will?—would claim our serious consideration. But in the former sense, as implying nothing more than that, in the original constitution and the ordinary course of Providence, the same effect is given to our prayers as to any other moral cause or condition, it seems to be exempt from all reasonable objection, and to afford a sufficient explanation of the difficulty.

The second "hypothetical solution" is that of those who hold that while God, in answering the prayers of men, does not ordinarily disturb the known or discoverable sequences of the natural world, yet His interference may be alike real and efficacious though it should take place at a point in the series of natural causes far removed beyond the limits of our experience and observation; and thus "the answer to prayer may be effectually given without any infringement on the known regularities of Nature." Dr. Chalmers adverts to this second solution in replying to an objection which might possibly be raised against the first, namely, that "we see no evidence of the constancy of visible nature giving way to that invisible agency, the interposition of which it is the express object of prayer to obtain;" and he suggests that, in the vast scale of natural sequences, which constitute one connected chain, the responsive touch from the finger of the Almighty may be given "either at a higher or a lower place in the progression," and that if it be supposed to be "given far enough back," it might originate a new sequence, but without doing violence to any ascertained law, since it occurs beyond the reach of our experience and observation. This solution we hold to be not so much an effective argument in favor of the efficacy of prayer, as a conclusive answer to a particular objection against it. It is sufficient to show that, with our very limited knowledge, we act presumptuously in deciding against the possibility of an answer to prayer such as may leave the established course of Nature unaltered; but there is no necessity, and no reason, for supposing that the responsive touch can only be given at a point to which our knowledge does not extend, or that, were our knowledge extended, we would have less difficulty in admitting it there, than in holding it to be possible at any lower term in the scale of sequences.

The third "hypothetical solution" is that of those who hold that a Divine answer to prayer may be conveyed through the ministry of angels, or the agency of intelligent, voluntary, and active beings, employed by God, in subordination to His Providence, for the accomplishment of His great designs. The existence of such an order, or rather hierarchy, of created intelligences is clearly revealed in Scripture; and it is rendered credible, or even probable, by the analogy of Nature, since we observe on earth a regular gradation of animal life from the insect up to man, and we have no reason to suppose that the gradation is suddenly arrested just at the point where the animal and the spiritual are combined. But not only their existence, their active agency also, as "ministers fulfilling His will," as "ministering spirits sent forth to minister to them who shall be heirs of salvation," is explicitly and frequently declared as well as exemplified in Scripture; and this, too, would be, on the supposition of their existence, in strict accordance with the analogy of Nature, which shows that the lower orders of being are placed under the care and control of the higher. Mr. Boyle, accordingly, makes frequent reference, in his Theological treatises, to the ministry of angels, as subordinate agents, through whose instrumentality many of the designs of Providence may be carried into effect; and President Edwards enlarges on the same theme.[212]

The fourth "hypothetical solution" is that of those who hold that God has so arranged His Providence from the beginning as to provide for particular events as well as for general results, and especially to provide an answer to the prayers of His intelligent creatures. This solution is more general than any of the three former, and may even be comprehensive of them all. It regards prayer as an element which was taken into account at the original constitution of the world, and for which an answer was provided, as the result of natural laws or of angelic agency, employed for this express end by the omniscient foreknowledge and wisdom of God. It is the solution that has obtained the sanction of some of the highest names in Science and Theology.

"I begin," says Euler, "with considering an objection which almost all the Philosophical Systems have started against prayer. Religion prescribes this as our duty, with an assurance that God will hear and answer our vows and prayers, provided they are conformable to the precepts which He hath given us. Philosophy, on the other hand, instructs us that all events take place in strict conformity to the course of Nature, established from the beginning, and that our prayers can effect no change whatever, unless we pretend to expect that God should be continually working miracles in compliance with our prayers. This objection has the greater weight, that Religion itself teaches the doctrine of God's having established the course of all events, and that nothing can come to pass but what God foresaw from all eternity. Is it credible, say the objectors, that God should think of altering this settled course, in compliance with any prayers which men might address to Him? But I remark, first, that when God established the course of the universe, and arranged all the events that must come to pass in it, He paid attention to all the circumstances which should accompany each event, and, particularly, to the dispositions, desires, and prayers of every intelligent being; and that the arrangement of all events was disposed in perfect harmony with all these circumstances. When, therefore, a man addresses to God a prayer worthy to be heard, that prayer was already heard from all eternity, and the Father of mercies arranged the world expressly in favor of that prayer, so that the accomplishment should be a consequence of the natural course of events. It is thus that God answers the prayers of men without working a miracle."[213]

"It is not impossible," says Dr. Wollaston, "that such laws of Nature, and such a series of causes and effects, may be originally designed that not only general provisions may be made for the several species of beings, but even particular cases, at least many of them, may also be provided for, without innovations or alterations in the course of Nature. It is true this amounts to a prodigious scheme, in which all things to come are, as it were, comprehended under one view, estimated and laid together: but when I consider what a mass of wonders the universe is in other regards, what a Being God is, incomprehensibly great and perfect, that He cannot be ignorant of anything, no not of the future wants and deportments of particular men, and that all things which derive from Him, as their First Cause, must do this so as to be consistent with one another, and in such a manner as to make one compact system, befitting so great an Author; when I consider this, I cannot deny such an adjustment of things to be within His power. The order of events, proceeding from the settlement of Nature, may be as compatible with the due and reasonable success of my endeavors and prayers (as inconsiderable a part of the world as I am) as with any other thing or phenomena how great soever.... And thus the prayers which good men offer to the all-knowing God, and the neglects of others, may find fitting effects, already forecasted in the course of Nature, which possibly may be extended to the labors of men and their behavior in general."[214]

"If ever there was a future event," says Dr. Gordon, "which might have been reckoned on with absolute certainty, and one, therefore, in the accomplishment of which it might appear that prayer could have no room or efficacy, it was just the restoration of the Jewish captives to the land and city of their fathers. And yet, so far from supposing that there was no place for prayer to occupy, among the various means that were employed to bring about that event, it was just his firm belief in the nearness and certainty of it that set Daniel upon fervent and persevering supplications for its accomplishment.... With regard to the rank which Daniel's prayer occupied among the various means or agencies that were to be employed in bringing about the object of it, he had good reason to believe that it was neither without a definite place, nor in itself devoid of efficacy.... He had been honored to vindicate the power and assert the supremacy of the Lord God of Israel; by the wisdom of his counsels and the weight of his personal character, he had paved the way for that decision in favor of the people of God to which the King of Persia was soon to be brought; and the whole business of his active and most laborious life was made to bear on the interests and the liberation of his afflicted brethren. And if God had thus assigned to the outward actions of His servant an important place in carrying into effect His thoughts of peace towards his penitent people, is it conceivable that He had no place in that scheme for the holy and spiritual efforts of the same servant? or that the aspirations of a sanctified spirit, the travailing of a soul intent upon the accomplishment of the Divine will and the manifestation of the Divine glory, should be less efficient or less essential in the execution of the Divine counsels, than the outward and ordinary agency of human actions? The whole tenor and the most explicit declarations of Scripture stand opposed to such a supposition; nor can I understand how a devout mind should have any difficulty in conceiving that it must be so. The agency of prayer is, indeed, a less obvious and palpable thing than that outward coöperation whereby mankind are rendered subservient to the accomplishment of the Divine purposes. But is it not an agency of an unspeakably loftier character? Is it not the coöperation of an immortal spirit, bearing the impress of the Divine image, and at the moment acting in unison with the Divine will? Is it not befitting the character of God to set upon that coöperation a special mark of His holy approbation, by assigning to it a more elevated place among the secondary causes which He is pleased to employ? And must there not be provision made, therefore, in the general principles of His administration, for fulfilling the special promise of His word, 'The Lord is nigh to all that call upon Him, to all that call upon him in truth.'"[215]

"We should blush," says Bishop Warburton, "to be thought so uninstructed in the nature of prayer, as to fancy that it can work any temporary change in the dispositions of the Deity, who is 'the same yesterday, to-day, and forever.' Yet we are not ashamed to maintain that God, in the chain of causes and effects, which not only sustains each system, but connects them all with one another, hath so wonderfully contrived, that the temporary endeavors of pious men shall procure good and avert evil, by means of that 'preëstablished harmony' which He hath willed to exist between moral actions and natural events."

"But should some frigid skeptic, therefore, dare
To doubt the all-prevailing power of prayer;
As if 'twere ours, with impious zeal, to try
To shake the purposes of Deity;
Pause, cold philosopher, nor snatch away
The last, the best, the wretched's surest stay.
Look round on life, and trace its checkered plan,
The griefs, the joys, the hopes, the fears of man;
Tell me, if each deliverance, each success,
Each transient golden dream of happiness,
Each palm that genius in the race acquires,
Each thrilling rapture virtuous pride inspires,
Tell me, if each and all were not combined
In the great purpose of the Eternal Mind?
