Though Charles Finney was immensely successful in his evangelism and revival ministry, he also saw the long-standing neglect of holiness in the life of the church. Setting himself to the task of correcting this problem, he both lectured and wrote on the doctrine of sanctification.
Principles of Sanctification is an expanded, edited and updated edition of Finney's Views of Sanctification first published in 1840. Compiler and editor L. G. Parkhurst has added the "Convention on Sanctification" which appeared in The Oberlin Evangelist, and also articles by two professors who worked with Finney at Oberlin College, James H. Fairchild and Henry Knowles. Together they present a clear and challenging message on what it means to live in a proper relationship with the Trinity.

For lay people and scholars alike, Finney's spiritual insight on the possibilities of holiness in the lives of believers.
