Harald Lindstrom's classic study of John Wesley's doctrine of sanctification remains perhaps the most accurate and comprehensive description we have of the theology of the founder of Methodism. Its accuracy stems from the fact that Lindstrom relied principally on Wesley's sermons to define his understanding of scriptural Christianity. Its comprehensiveness reflects the fact that John Wesley saw, and spent his lifetime explaining, that the promise of salvation was the central theme of biblical theology and that the experience of sanctifying grace was the essence of salvation.

A Plain Account of Christian Perfection by John Wesley is about the theory of perfection according to Christian theology. Excerpt: "1. WHAT I purpose in the following pages is, to give a plain and distinct account of the steps by which I was led, during the course of many years, to embrace the doctrine of Christian Perfection. This I owe to the serious part of mankind; those who desire to know all the truth as it is in Jesus. And these only are concerned with questions of this kind. To these I would nakedly declare the thing as it is, endeavoring all along to show, from one period to another, both what I thought, and why I thought so."

The Wesleyan understanding of baptism with the Holy Spirit and other aspects of entire sanctification.

A rich articulation of John Wesley's theology that is appreciative of the old and mindful of the new, faithful to the past and attentive to the present. This work carefully displays John Wesley's eighteenth century theology in its own distinct historical and social location, but then transitions to the twenty-first century through the introduction of contemporary issues. So conceived, the book is both historical and constructive demonstrating that the theology of Wesley represents a vibrant tradition. Cognizant of Wesley's own preferred vocabulary, Collins introduces Wesley's theological method beginning with a discussion of the doctrine of God. "In this insightful exposition the leitmotif of holy love arises out of Wesley's reflection on the nature of the divine being as well as other major doctrines." (Douglas Meeks)

In this analysis of Charles' theology of sanctification, the centrality he accorded to resignation is uncovered to show a positive attribute involving acts of intention, desire and offering to God.
