Please note that most of these prayer focused books by Stormie Omartian are offered as (1) a book, (2) a study guide, and (3) a prayer book. The original book is the BEST purchase if you are looking for just ONE purchase. THIS book is the first, the original "Power of a Praying Parent" book. The book is broken down into 31 chapters each focusing on a different area you can direct your prayer for your children. Each chapter has an explanation/teaching that usually includes a real life example from the author and is followed by a sample prayer as well as a page of related Bible verses. It is a must have for every parent and the 31 chapter format is a great way to incorporate the teaching into your every day life by covering one each day and starting over each month. The chapters are short, but very powerful. I highly suggest making the purchase and then making a commitment to read from it daily. It is not a book to just merely read, but a book to mediate on and live by. As an added bonus there is an extra chapter on praying for adult children which includes a specific prayer for each topic covered geared towards adult children (Note that she has also written a new book that specifically deals with adult children, "The Power of Praying for Your Adult Children"). Also, there is an appendix covering praying together with other parents.
Beyond this book you can also purchase the study guide which does not include prayers or any content from this book, it is only a book of study questions to help inspire thought and discussion. The third book available is a small (perfectly pocket-sized) book that is JUST prayers, but handy to carry around with you always. I highly recommend all of the books; just be aware of which one you are purchasing, each series uses the same cover art on all three books.
