Pohle’s volume on grace explores the centrality of grace in Christian belief and practice. He writes at length on the relationship between unbelief and grace, as well as God’s will to save. A significant portion of this volume is devoted to free will, including the understanding of free will in the writings of Luther and Calvin, along with the Council of Trent. Pohle also deals with justification and sanctification—arguably the central and most controversial doctrines of the Reformation.
