"This book has come to you. Since nothing can come to you except that which belongs to you or that which you need for your growth, accept it as an answer to a need, and do not let the book go until it gives you a blessing."—Stella Terrill Mann, Preface

"This book really did change my life….If you could read only one book on prayer, I would unhesitatingly urge you to choose this one."—Marjorie Holmes, bestselling author of I've Got to Talk to Somebody, God
