When a minister obtains this revival he preaches very differently from his former manner. It is very hard work to preach when the head aches and when the body is languid, but it is a much harder task when the soul is unfeeling and lifeless. It is sad, sad work—painfully, dolorously, horribly sad, but saddest of all if we do not feel it to be sad, if we can go on preaching and remain careless concerning the truths we preach, indifferent as to whether men are saved or lost! May God deliver every minister from abiding in such a state!
