A book on faith has been for years my hope and intention. And now it comes to final form during the most terrific war men ever waged, when faith is sorely tried and deeply needed. Direct discussion of the war has been purposely avoided; the issues here presented are not confined to those which the war suggests; but many streams of thought within the book flow in channels that the war has worn. Since the conflict had to come, I am glad for this book's sake that it was not written until it had Europe's holocaust for a background. Against one misunderstanding the reader should be guarded. If anyone approaches these studies, expecting to find detailed and special views of Christian doctrine, he will be disappointed. The perplexities of mind and life and the affirmations of religious faith, with which these studies deal, lie far beneath sectarian doctrinal controversy. I have tried to make clear a foundation on which faith might build its thoughts of Christian truth. And while I have spoken freely of God and Christ and the Spirit, of the Cross and life eternal, I have not intended or endeavored a complete theology. - Preface.
