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 only work by which its author is popularly known. It has high merits of style, being lucid and pointed to a degree. In a tract entitled The Absolute Unlawfulness of Stage Entertainments (1726) Law was tempted by the corruptions of the stage of the period to use unreasonable language, and incurred some effective criticism from John Dennis in The Stage Defended.
