Watching the video and doing the participants guide is a must if you are doing 'The Story'. It brings it all together from a different perspective than normal. It helps make it more real and personal. It is an absolute must if you are doing the study.
I was given the book The Story by my bible study teacher. When I saw the study guide for the DVD, I was a little apprehensive about ordering it since I didn't have the DVDs. I decided to order the study guide anyway, and have been very pleased. I've found the questions to be very helpful in understanding what I'm reading in the book.
