"This book revolves around the Christian's most heartfelt questions of all. You cannot observe unmerited human suffering without asking, whatever is God doing? You cannot pray hard for things which seem unlikely to come to pass without wondering whether you are wasting your time. You cannot try anything in the name of God without encountering obstacles and enmities which throw you into the kind of mental tangle which this book attempts to sort out. For the book follows with tenacity a train of thought about God's way of dealing with his children which is basic and elemental to the business of forcing experience and faith into some sort of logical relationship."
