It is intended to be used in a small group setting for a six week study. It asks that you read only one page a day, and spend 25 minutes reading, making notes in the book and praying. If you don't take the time each day to do what it suggests, you will miss that growth that it promises.
I have used this workbook to lead small group studies at least four times. It has changed more lives than any other book I have ever used.
