Holiness: Its Nature, Hindrances, Difficulties, and Roots is perhaps J. C. Ryle’s best-known and, arguably, best-loved book. Although many things have changed since 1877, when this book was first published, one thing remains the same: real practical holiness does not receive the attention it deserves. It was to remedy this attention deficit, and to counter false teaching on this most important subject, that Ryle took up his pen.

Holiness, as with all of Ryle's works, is clear and concise, penetrating and practical.
