"The Book of Concord should be in every Lutheran home. If a person isn't familiar with this book, he'll think, 'That old book is just for pastors. I don't have to preach. After working all day, I can't sit down and study in the evening. If I read my morning and evening devotions, that's enough.' No, that is not enough! The Lord doesn't want us to remain children, blown to and fro by every wind of doctrine; instead of that, He wants us to grow in knowledge so that we can teach others."
