Henry Van Dyke 
What Peace Means [PDF ebook] 

These days, the concept of "peace" has grown a little worn through overuse. Having been appropriated by so many different groups at every point on the ideological spectrum, the promise of peace has been rendered so abstract as to be almost meaningless. In this series of sermons, Henry Van Dyke relates the concept of peace to Christian faith and spiritual growth, dispensing straightforward advice to help believers achieve a sense of serenity and fulfillment.
