This is a fantastic book! There are a number of free pdf versions around on the internet which I found difficult and hard going to read. However this particular version is brilliant and although most of the text probably follows what could well be described as an out of date style of writing and grammar nothing has been lost - the message is clear. The supporting notes in the margins and cross references to Biblical texts are most helpful. There are a few sections that have to be read a number of times in order to gain an understanding of what John Bunyan meant but once the meaning has been grasped all should be clear. This is probably because some of the text uses proverbs that were in common use in the 16th and 17th centuries. Well worth the money and worth reading. I've not read many books that I couldn't put down but this is one of them!
