The Introduction to this edition discusses the nature of Wesley's Journal, places it in the context of autobiography as a genre, examines its construction, and discusses Wesley's frame of mind during its writings. One of the major functions of this scholarly edition is to reveal John Wesley "in the light of his involvement in the crowded forum of eighteenth century theological debate." Wesley's writings are saturated with references to Scripture, the Latin and Greek classics, the early Church Fathers, his theological predecessors, English poets and playwrights, and those "natural philosophers" exploring the wonder of God in creation.
