Martyn Lloyd-Jones is perhaps the greatest expositional writer of the twentieth century without challenge. It is clear that this work in Romans MUST have been his dearest work. His great love of God and his clear love of the "word" runs throughout. I dare say that you will not find a grander composition on assurance outside of scripture itself. This is not "easy" reading and should be approached with the same reverance and dedication as scripture. Once you are committed to the task you will have great difficulty putting them down. While I am not accustomed to spending large sums of money on books that will only end up on a shelf collecting dust, I can assure any believing Christian that you will read these over and over. What a wonderful gift to yourself and your childrens children.
