But who were these persons who became aroused to a sense of the exigencies of the times, and saw that the danger which threatened the kingdom of God in Germany was now scarcely less than when Tilly was leading his maddened hordes through the fair fields and over the ruins of those once happy towns? Some of the clergy were the first to indicate new life. They preached with more unction, and addressed themselves to the immediate demands of the parish, especially to provide for the orphans and widows of those who had fallen in battle. Certain ministers who had spent their youth in vain theological wrangling, preached sermons which contained better matter than redundant metaphor and classical quotations. Mueller and Scriver serve as fitting illustrations of the improvement. They avoided the extended analytical and rhetorical methods long in use, and adopted the more practical system of earnest appeal and exhortation. The clergy needed not to wait long before beholding the fruit of their labors. For a better spirit manifested itself also among the lower classes. A singular interest arose in sacred music. Not only in those venerable Gothic Cathedrals, so long the glory of the Roman Catholic Church, but in the field and the workshop there could be heard the melodies of Luther, Sachs, and Paul Gerhard. Young men appeared in numbers, offering themselves as candidates for the ministry. But let it not be supposed that these encouraging signs were universal. While the eye of faith could read the most decided lessons of hope, the religious dearth was still wide-spread. Nor was it unlikely that in a short time it would triumph over all the efforts for new life. When Spener rose to a position of prominence and influence, he saw, as no one else was able to see, the real danger to the cause of truth; and those affecting descriptions which we find among his writings, revealing the real wants of the latter half of the seventeenth century, show how keenly his own heart had become impressed by them. It was very evident that the Lutheran Church would require a long period for self-purification, if indeed she could achieve it at all. The shorter and more effectual way would be to operate _individually_ upon the popular mind. And does not the entire history of the Church prove that reform has originated from no concerted action of the body needing reformation, but from the solemn conviction and persevering efforts of some single mind, which, working first alone, has afterward won to its assistance many others? Its work then reacted upon the parent organization in such way that the latter became animated with new power.
