This small book is a searching treatment of the subject of personal holiness in four sermons on “the spirit of holiness” (Rom. 1:4). The first sermon considers the Author, nature and necessity of holiness; the second, the incipient principle of holiness as developed in regeneration; followed thirdly by a treatment of holiness negatively, as exhibited in the mortification of sin, and then positively, in the work and progress of Sanctification. James Harrington Evans was an earnest preacher and writer of the first half of the nineteenth century. In a day when holiness was highly regarded, this work was likewise. Spurgeon wrote that Evans “was a great teacher. A more sound, earnest, and instructive divine never lived.” 134pp. (preface i-iv, Sermons 1-120 ).
