I would like to go through Pilgrims Progess via a devotional with my wife. The only one I've seen is one by Cheryl Ford: http://www.amazon.com/dp/1581340303/?tag=baptis04-20 Im not looking for anything deep theologically--just a walk through the book in bite size chunks for us to go through. Has anyone here gone through a devotional based on this book? If so, what devotional was this? Was the devotional worth the time, or would you have gone through another book if you had to do it again?
