In recent years much work has been done to grasp the intricacies of Wesley's theology. However, most of this work has been thematic in organization, studying Wesley's thought according to a topical or systematic outline. The weakness of this approach, argues author Kenneth J. Collins, is that it fails to demonstrate the evolution and changes of Wesley's theology over time. Instead, a historical presentation is called for, one that examines the development of Wesley's theology across the span of his long and eventful theological career. Collins extensively examines the primary sources and demonstrates an intimate knowledge of the different social locations in which Wesley's theological thinking took place, making John Wesley: A Theology Journey necessary reading for anyone wishing to grasp the broad scope of the Methodist leader's theological thought and contribution.
