Rereading good books is a great past time. I first bought this book and read it in 2004 while in Scotland one summer helping a missionary. It was in a small used book store in North Berwick not far from the fish and chips stand (both were in my usual circle of evening walking). Ironside (1876-1951) was saved though the Salvation Army but had to depart from it because of its sinless perfection (eradification of the old nature) teaching. In writing a refutation of that system of doctrine he did the church a great service and made a good contribution to the subject of holiness and our walk with God. No doubt, some of the best writing on a subject comes from one who had to study the Scripture and change from a formerly held conviction. If you are interested in what the Bible says about holiness, sanctification, sin in a believer, and the Christian walk, this would be a good read from a well-known and solid Bible teacher. Ironside was a Canadian born Bible teacher and pastor who pastored Moody Church in Chicago from 1929 to 1948.
