I wouldn't be at all surprised if this book started out as a series of sermons. Each chapter reads like a sermon given in a friendly evangelical church: inspiring, encouraging, with nothing too deep or challenging or complicated or critical. As to the intended audience, the authors mention Chuck Swindoll as though they expect readers to know who he is. In fact, the book is reminiscent of Swindoll, and fans of Swindoll should find this book right up their alley. Others may or may not find it helpful, depending on where they're coming from and where they are in their spiritual lives.
The book also has a firm foundation of the Bible, there are many references and quotes from the Bible that are used correctly. I appreciate this I was kinda unsure if I wanted to read this book at first as I was a bit weary thinking this was one of those liberal Christians (who aren't really Christians) and Jesus Seminar kind of writings. Luckily for me it wasn't and it was a true spirited Jesus believer sort of book.
Its one of many books out there, its not something that I will say "You have to read" but still it is a good book. Nothing new, but still well written and well developed thoughts on being a Christian.
