This biography tells the story of John Wesley's colourful and dramatic life, beginning with his childhood and his family background, looking especially at the influence of his powerful and austere mother, Susannah.

The author then goes on to examine Wesley's school and university careers (including the Holy Club), his mission to Georgia and finally his conversion and mission to England - including the organisation of methodist societies. Key issues in Wesley's life, such as his renunciation of wealth and the role of women, are given prominent treatment as is an assessment of Wesley's long-term impact both in this country and abroad.
