Here is an expanded, edited and updated edition of Finney's Views of Sanctification first published in 1840. This new volume includes Finney's Letters on Sanctification which appeared in the Oberlin Evangelist, and also includes articles by two professors who worked with Finney at Aberlin College, James H. Fairchild and Henry Kowles. Principles of Sanctification presents Finney's understanding of what it means to live in proper relationship with the Trinity. The Bethany House book edited by Timothy Smith entitled The Promise of the Spirit includes Finney's sermons on sanctification published prior to 1840; this volume contains messages on the subject which were published during 1840. This book will help the reader to a clearer understanding of the doctrine of sanctification and to Finney's theology.

'The Gospel Mystery of Sanctification' by Walter Marshall, first published in 1692, is one of the classic works of Christian spirituality. It is a deep and rich biblical study of sanctification - how Christians grow in holiness and become more like Jesus. In a day when Christians are very prone to pursue self-help methods to grow in obedience to Christ, Walter Marshall lays out the biblical way of growth: obedience comes as Christians live by grace, in union with Christ, by faith. Growth comes, as Paul says in Galatians 2:20, through "Christ living in me." The message of this book is so important for Christians today, it is essential that it be rewritten in contemporary English.
