Herein is a most discriminating study of the basic differences between historic Calvinism and Arminianism and the developments in both theological traditions that have created the mounting barriers to the understanding of each other's position. Dr. Wynkoop deals authoritatively with the critical issues, and incisively cuts through the prevalent fuzzy theological concepts, but all with delicacy and understanding. The monumental contribution of John Wesley in defining the doctrine of sanctification is a key emphasis in the book, along with the central issue of Christian assurance.
