First published in 1939, this book is a phenomenon in contemporary spiritual writing. The message that every Christian man and woman, whatever their place of work or calling, is called to sanctity has touched countless lives; this work offers a starting-point for a prayer which finds Christ in all the experience of living. A special feature of this new edition is the footnotes, drafted not only for those approaching the book as a tool to help them pray, but having in mind also readers studying the text as an example of 20th Century Spanish literature. This is a revised annotated bilingual edition, has parallel Spanish and English texts.
