A convert to Christianity from the Qadiri Order, John A. Subhan is well-known for his seminal work, Sufism: Its Saints and Shrines. Sufism prepared him for faith in Jesus and his Injil. His Sufi background and intimate knowledge of its beliefs and practices enabled him to explain Sufism to others. All ten chapters in Sufism are interesting not least the chapter eight which contains an engaging comparative discussion of Sufism in the broader Hindu context. It is a must read for all, not only because it is a window into the world of a great Sufi convert but also because it provides us with a view of his world, some or most of which still continues.
