Wingspread: Albert B. Simpson, a Study in Spiritual Altitude (Unabridged‪)‬

Wingspread is the biography of A.B. Simpson, written by A.W. Tozer. A pastor and missionary, Simpson's work became what is now the Christian and Missionary Alliance, a denomination characterized by its Christ-centered teaching and emphasis on missions. Simpson's influence saw a convergence of Calvinistic doctrine with the holiness movements of the late 19th century. Simpson and the C&MA had an enormous influence upon the evangelical foreign missions movement of the 20th century. The influence was also felt in the holiness movement with the formation of the Assemblies of God. Simpson is an interesting and key figure, in no small part due to his teachings on the fourfold Gospel and on healing.
