1. OverallI was always interested in Rev. John Wesley, although I'm attending Reformed Church. In this 'commemoration of the Three Hundred Anniversay of the birth of John Wesley', Kenneth Collins explained or introduced not only the life of John Wesley, but also the transiton of theological positon of John Wesely. Especially, this 'journey' shows, without any screening, the weakness or follies of John Wesely in such a candid way, so I got so much 'comfort' for this. Even John Wesley DID make mistakes several times just like me, and his 'theological journey' went on all through his entire life. 2. StyleAlthough this book follows the chronological order, it usually shows five distinct points in 'essential' part of his life : 1) background 2) accident 3) journal written by Wesley at that time 4) the evaluation of the accident by relevant modern books and 5) relevant 'disclaimer' part of journal which was written in later days. Furthermore, Collins from time to time provide compact summary for the essential or critical theological thesis, so it really helped me a lot in understanding Wesley's theology and its TRANSITION. Now I understand, basically although, where is the difference between the Calvinistic view and Wesleyan-Arminian view, and its impact in the context of actual lives in 18th century, and perhaps in 21st century. Lastly, this book refers the soucing books or sermons so detailed manner, so it helped me acquainted with the works of John Wesley, which enabled me to discern which book to read afterwards. I felt I'm reading at least two or three books at a time (in this small volume!) : biography, theological book, and devotional book. I really enjoyed this book. I highly recommend this book, to Methodist or even to any 'reformed - minded' person who wants to understand Rev. John Wesley.
