Holiness, It's Nature, Hindrances, Difficulties and Roots by J C Ryle and published by Classics.
J C Ryle writes “The papers contained in this version are a humble contribution to a cause which is exciting much interest in the present day, I mean the cause of Scriptural holiness, it is a cause which everyone who loves Christ, and desires to advance His kingdom in the world, should endeavour to help forward. Everyone can do something, and I wish to add my mite.
The reader will find little that is directly controversial in these papers. I have carefully abstained from naming modern teachers and modern books. I have been content to give the result of my own study of the Bible, my own private meditations, my own prayers for light, and my own reading of old divines. If in anything I am still in error, I hope I shall be shown it before I leave the world. We all see in part, and have a treasure in earthen vessels. I trust I am willing to learn.”
