In a foreword addressed to the king, Kingo states that "he has written these hymns with the hope that they might serve to edify his fellow Christians, advance the teaching of the Gospel and benefit the royal household at those daily devotions which it is the duty of every Christian home to practice". He prays, therefore, he continues, that "the king will graciously bestow the same approval upon this work that he has so kindly given to his previous efforts, and thereby encourage him to continue his endeavor until the Danes shall possess a hymnody that they have neither begged nor borrowed from other nations. For the Danish spirit," he concludes, "is assuredly neither so weak nor so poor that it cannot fly as high toward heaven as that of other peoples without being borne upon strange and foreign wings". Commenting on the content of the book, Kingo further explains that he expects sensitive readers will discover imperfections in his work which he himself has failed to see, and that it would please him to have such blemishes called to his attention so that they might be corrected in future issues. His choice of tunes will, he fears, provoke criticism. He has set a number of hymns to the melodies of popular songs in order that "those, who for the sake of its tune, now gladly listen to a song of Sodom may, if they be Christians, with the more pleasure use it with a hymn about Zion. By examining the work of other hymnwriters possible critics might assure themselves, however, that he had in this matter only followed their example." But Kingo need not have apologized for his choice of tunes, for they were on the whole fine and were received without objection. It would be difficult to overstate the enthusiasm with which Kingo's hymns were received. Within a few years they were printed in numerous editions and translated into several foreign languages. Their enthusiastic reception was well deserved. Viewed against the background of literary mediocrity that characterized the period, Kingo's hymns stand out with amazing perfection. Danish hymnody contained nothing that could compare with them, and other countries, as far as morning and evening hymns were concerned, were in the same position. Paul Gerhardt's fine hymn, "Now Rests Beneath Night's Shadow", which was written twenty years earlier, had been ridiculed into disuse; Ken's famous morning hymn dates from twenty years later; and none of these are as fine as the best of Kingo's. As might be expected, the hymns are not all of the same merit. Some of them are exceedingly fine; others show the defects of an imperfectly developed language and a deficient literary taste. In the matter of style and form the author had almost nothing to guide him. It is not surprising, therefore, that his work shows crudities which no present day writer would commit, but that it should contain so much that is truly beautiful, even when measured by the standards of today.
