William Law was a Church of England priest who lost his position at Emmanuel College, Cambridge when his conscience would not allow him to take the required oath of allegiance to the first Hanoverian monarch, George I. His personal integrity, as well as mystic and theological writing greatly influenced the evangelical movement of his day as well as Enlightenment thinkers such as the writer Dr Samuel Johnson and the historian Edward Gibbon.A Serious Call to a Devout and Holy Life (1728), together with its predecessor, A Practical Treatise Upon Christian Perfection (1726), deeply influenced the chief actors in the great Evangelical revival. John and Charles Wesley, George Whitefield, Henry Venn, Thomas Scott, and Thomas Adam all express their deep obligation to the author. The Serious Call also affected others deeply. Samuel Johnson, Gibbon, Lord Lyttelton and Bishop Home all spoke enthusiastically of its merits; and it is still the work by which its author is popularly known. It has high merits of style, being lucid and pointed to a degree.
