"Every attempt at revival of religion which proves a failure,—and fail it must without the presence of God,—leaves the Church in a worse condition than it was before; because, if it should prove a failure, from the want of any stir at all; then God's people fall back into their former lethargy, with an excuse for continuing in it; or if a false stir be made, a reaction follows of a most injurious character. I suppose the worst time in the Christian Church is generally that which follows the excitement of a revival; and if that revival has had no reality in it, the mischief which is done is awful and incalulable. If no excitement shall come at all, the mischief is still as great; God's people, being disappointed, have little heart to listen to further exhortations to future zealous action, become contented with their Laodicean lukewarmness, and it becomes impossible to bestir them again. If a revival should apparently have success and yet God be not in it, perhaps this is even worse. The wild-fire and madness of some revivals have been a perfect disgrace to the common sense of the age, let alone the spirituality of the Church."
—C. H. Spurgeon (1834-1892)
