This book looks at the experience of prayer, the needs through which it arises, the ends it seeks. It considers the thought of God addressed in prayer, and examines the prayer as a form of words, emphasizing its kinship with poetry. It deals with the available source-material for constructing prayers, from liturgical and devotional material to the rich literature of the imagination. There are suggestions for preparation and delivery, including some comments on the function of pastoral prayer in wartime. The study is concluded with some of the author's prayers, chosen to illustrate the principles which the book sets forth. This book is for ministers and for others having part in public worship, but of great interest to all individuals who pray privately, for the discussions of content and of words, rhythms, themes, moods, movements etc., will help each individual give color and dimension to his own prayers so that they can take root and flower more abundantly in his own heart.
