Purpose of this book is to learn the solutions given in God's Word for overcoming all the foes of happiness and peace of mind. To learn how to live the Christian life and to grow toward spiritual maturity by correcting and/or improving our basic attitudes toward life and our fellowman.
Overall, this is a book filled to the brim with great content and wonderful illustrations. As a preacher, there is a lot about this book that could easily be taken and used for sermons. The layout of the book does leave some things to be desired though. Because every chapter is basically a list of bullet points, it can be rather tedious to read at times.
