A certain few books from church history are timeless classics. Though written nearly 150 years ago, J. C. Ryle's work "Holiness" is one of those classics. Ryle's book has become a standard, go-to work on the topic of sanctification and personal holiness. As today, he was battling a widespread, general attitude that was unconcerned about holiness and considered that to be the calling of only the "higher life" believers. On the other hand, he also warns against the opposite error that teaches holiness results in sinless perfection in this life. Instead he rightly teaches that real holiness is a heart issue and flows from the genuine Christian's vital connection to Christ by faith.
