This passage is part of a sermon by C.H. Spurgeon in 1866, and so it is a not a simple read, but will benefit any who will put in the time to understand.
If revival is confined to living men we may further notice that it must result from the proclamation and the receiving of living truth. We speak of “vital godliness,” and vital godliness must subsist upon vital truth. Vital godliness is not revived in Christians by mere excitement, by crowded meetings, by the stamping of the foot, or the knocking of the pulpit cushion, or the delirious bawlings of ignorant zeal; these are the stock in trade of revivals among dead souls, but to revive living saints other means are needed. Intense excitement may produce a revival of the animal, but how can it operate upon the spiritual, for the spiritual demands other food than that which stews in the fleshpots of mere carnal enthusiasm. The Holy Ghost must come into the living heart through living truth, and so bring nutriment and stimulant to the pining spirit, for so only can it be revived. This, then, leads us to the conclusion that if we are to obtain a revival we must go directly to the Holy Ghost for it, and not resort to the machinery of the professional revival-maker. The true vital spark of heavenly flame comes from the Holy Ghost, and the priests of the Lord must beware of strange fire. There is no spiritual vitality in anything except as the Holy Spirit is all in all in the work; and if our vitality has fallen near to zero, we can only have it renewed by him who first kindled it in us. We must go to the cross and look up to the dying Savior, and expect that the Holy Spirit will renew our faith and quicken all our graces. We must feed anew by faith upon the flesh and blood of the Lord Jesus, and so the Holy Ghost will recruit our strength and give us a revival. When men in India sicken in the plains, they climb the hills and breathe the more bracing air of the upper regions; we need to get nearer to God, and to bathe ourselves in heaven, and revived piety will be the sure result.
