I don't see that at all. Can you point me to the relevant paragraphs?
Here are some that show he is putting his book above others - on a level with the Living Word. He is saying that it is his book, not the Word, not the Holy Spirit who will give you spiritual life. It is subtle, but it is very definetly there. Not all will see it though.
This is more than a book; it is a guide to a 40-day spiritual journey that will enable you to discover the answer to life’s most important question: What on earth am I here for? By the end of this journey you will know God’s purpose for your life and will understand the big picture—how all the pieces of your life fit together. Having this perspective will reduce your stress, simplify your decisions, increase your satisfaction, and, most important, prepare you for eternity.
This book is divided into 40 brief chapters. I strongly urge you to read only one chapter a day, so you will have time to think about the implications for your life. The Bible says, “Let God transform you into a new person by changing the way you think. Then you will know what God wants you to do.” One reason most books don’t transform us is that we are so eager to read the next chapter, we don’t pause and take the time to seriously consider what we have just read. We rush to the next truth without reflecting on what we have learned.
Don’t just read this book. Interact with it. Underline it. Write your own thoughts in the margins. Make it your book. Personalize it! The books that have helped me most are the ones that I reacted to, not just read.
