Such and so helpless, even now, is natural theism showing itself; and in the dim and momentous changes that are coming over things, in the vast flux of opinion that is preparing, in the earthquake that is rocking the moral ground under us, overturning and engulfing the former landmarks, and re-opening the graves of the buried lusts of paganism, it will show itself very soon more helpless still. Its feet are on the earth, only. The earth trembles, and it trembles: it is in the same case as we are. It stretches in vain its imploring hands to heaven. But the heaven takes no heed of it. No divine hand reaches down to it to uphold and guide it. This must be the feeling, I believe, of most honest and practical men, with regard to natural religion, and its necessary practical inefficiency. Nor will the want it necessarily leaves of a moral rule be the only consideration that will force this conviction on them. The _heart_, as the phrase goes, will corroborate the evidence of the _head_. It will be felt, even more forcibly than it can be reasoned, that if there be indeed a God who loves and cares for men, he must surely, or almost surely, have spoken in some audible and certain way to them. At any rate I shall not be without many who agree with me, when I say that for the would-be religious world it is an anxious and earnest question whether any special and explicit revelation from God exist for us; and this being the case, it will be not lost time if we try to deal fairly and dispassionately with the question.
