This book is the study of prayer as a means of encountering God in this life. Father Green stresses that as part of this communication we need to listen. Prayer is not just a matter of praise and petition, especially in prefabricated forms. He prefers to use the term “opening” our minds and hearts to God, rather than ‘raising’ as it is in the catechism. Father Green writes in an accessible, warm-hearted style and is at times quite humorous, especially when using analogies to illustrate his meaning. He maps out stages of spiritual development for those dedicated to a life of prayer, and he gives practical advice to all who strive to make their prayers more effective. This is a wise book, a holy book, and above all a helpful book for anyone wanting to grow closer to God.
