The subconscious mind will furnish the fitting quotation, whether he writes his sermon or speaks _ex tempore_. In unexpected emergencies, when there is no time to leaf over the hymnal for a verse to be sung, the mind automatically supplies it. In personal work, in cheering the sick, in comforting those who mourn, in inspiring the lagging and discouraged ones, the apt quotation will be exceedingly effective. There are moments in a service, unexpected episodes of an emotional character, climaxes of feeling in a discourse, when a verse of a hymn sung by the congregation will exceed in impressiveness any oratorical outburst; if the minister can trust his memory, he can carry the faltering memories of his people and realize an effect otherwise impossible, not only not losing any momentum, as he would if it were necessary to refer to the hymnal, but indefinitely increasing it. The great hymns of the Church should be made a part of his mental furniture, become a large share of his clerical working capital. He should not be satisfied to have less than a hundred hymns at his mental fingers’ ends for efficient use at a moment’s notice. V. A STUDY OF METHODS OF USE But it is not enough to gather the materials and study the individual hymns. A magazine of blasting powder has immense possibilities of power; but unless methods are invented for applying that power to desired ends, it is a liability and not an asset. Having learned all about hymns, the next study is how efficiently to use them, to organize the best methods of exploiting the social, mental, and spiritual values their singing offers. _Using Hymns in Sermons._ Few ministers utilize the possibilities of apt Scripture quotations in their sermons; fewer still know how to draw on the treasures found in their hymnals to increase interest and intensify emotion. In many cases the very finest climax to a section of a sermon, or to the sermon itself, will be found in one or more verses of a hymn which brings the emotion of the theme to its high culmination. There is no lack of material; for the expression of every Christian doctrine that lends itself to lyric feeling there are intense and poignant phrases and lines steeped in transcendent emotion. Abstract truth has intellectual value of course, but has spiritual value only when transmuted into the gold of intense conviction in the heart of true believers. It is the genuine hymn that raises the temperature to the transmuting point, if properly introduced and emotionally used. _Studying Responsiveness of the Congregation._
