I bought this book after reading 'The Enemy Within' by Kris Lundgaard, wanting to spend more time studying the defeat of sin in my day to day life. This book is a detailed guide on how a Christian can be equipped for the ongoing struggle of sin from one of the best theologians to have lived, and has been a challenge both to me and my understanding of the English language (I recommend a good dictionary for one or two words). The book itself is full of biblical quotes (I have been backwards and forwards in my Bible continuously) all of them relevant truths. This book is best read quickly if you are new to Owen (and want to avoid getting bogged down deciphering the language) though you should be able get the general message of his 'discources' (chapters/essays). If you are looking for a general modern overview of the topic read ENEMY WITHIN THE PB but if you want depth, read this. It's worth persisting with this book as it is a most in depth book on this topic. I did and have been greatly encouraged.
