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.
