Often called the greatest of the post-Reformation English mystics, William Law was born in King's Cliffe, England, became a Fellow of Emmanuel College, Cambridge and was ordained a priest in the Anglican Church. After losing his position at Cambridge for refusing to take the Oath of Allegiance to George I, he became the center of a small spiritual community. He was a religious guide to the Gibbon family and included among his disciples John and Charles Wesley.
His practical work as a spiritual director-as expressed in this, his best-known piece, A Serious Call to a Devout and Holy Life-deeply influenced the English Evangelical Revival. The Oxford Dictionary of the Christian Church says this of the book: "The simplicity of its teaching and its vigorous style soon established the work as a classic, which has probably had more influence than any other post-Reformation spiritual book except the Pilgrim's Progress." In his later years Law became an intense admirer of the teaching of Jacob Boehme on the coincidence of opposites. He gave this doctrine an original turn in his little-known but exquisite mystical treatises-the most important being The Spirit of Love. This double selection, edited from first texts instead of reprints, demonstrates the range of Law's thought and his development as a genius of style and devotion.
