The prelude must be calculated to cover disturbing sounds and to call the people to order—an entirely different type of prelude from that used in the previous hypothetical situation. Once quiet and order are secured, the music may begin a quieter, more religious movement. But the high ecstasy of the Long Meter Doxology is out of the question. An earnest Call to Worship by the preacher, and a quiet sentence or introit by the choir, will hush the people’s minds into sympathy with the invocation, that may possibly be somewhat longer and more earnest, which in turn will prepare them for a sincere and thoughtful participation in the “Gloria Patri.” The wise and observant preacher will have been able to anticipate their state of mind and decide whether they are ready to Sing with sincerity “O day of rest and gladness,” “Safely through another week,” or the more elevated “Holy, holy, holy, Lord God Almighty,” or “Before Jehovah’s awful throne.” By the time this hymn is sung, the fate of the service has practically been settled. The people will have been won and are ready to go on to a deeper interest and to a fuller yielding of themselves to the influence of the service; or they are dull and unresponsive, even somnolent, with an unconscious resentment that they have not been stirred and quickened. The failure of the service is assured, unless a miracle happens. If the minister is a slave to the conventional order of service, that miracle will not happen. He may be so complacent over the smooth unfolding of the wonted numbers as not to recognize that the interest in the minds of his people has dropped. In such a situation the best means to redeem it is a hymn with a profound appeal. But it cannot function, if it is used in the ordinary, conventional way. If the minister is alert and senses the stupor that is shadowing the minds of his people, and if the success of his service is more important to him than the mechanical regularity of the usual order of events, he can bring the miracle to pass by the use of the next hymn in an unexpected, thrilling way.
