Success and the Christian: The Cost and Criteria of Spiritual Maturity by A W Tozer and published by Wingspread.
In this insightful and prophetic volume, Tozer shows how we can recognize and clear away the stumbling blocks that keep us from a dynamic relationship with the Savior. He asks what is authentic spiritual success? Tozer's answers, as one might expect, cut across much of contemporary thought such as "Spiritual Prefection Defined"; Formula for Christian Success"; "Communion of Saints" and much more besides!
