This book is about how God’s Word shapes and rules our devotion to him. What is the best way of talking about this? ‘Spirituality’ is what many people call it, but this is not the ideal word. It can mean a great many things, some of them very far removed from anything the Bible teaches. ‘Piety’ is another possibility, but this is sometimes used in a rather negative way. Preferable is ‘Devotion’. When we speak of a couple being ‘devoted’ to each other, we mean that their relationship is strong, loyal, and loving – which is how we should relate to God.
