I didn’t read this all at once – I read it bit by bit, for a men’s Bible study class. So it’s a bit harder to review than normal.
The book is a discussion of “holiness,” and how and why should pursue it by reducing the amount of sin in our lives. It explains why we should seek holiness, why that’s difficult, and the difference it can make in our lives.
I don’t remember much in the way of practical advice, but, again, my reading of it was a little odd. There’s a study guide at the back which takes up a fair part of the book, so I’m assuming it’s used quite often in groups.
