Book excerpt: Arminianism is rife within the modern evangelical church, with vocal proponents attacking the orthodox teaching of Calvinism. One such critic is Leighton Flowers, the director of Evangelism and Apologetics for Texas Baptists who leads the Soteriology 101 ministry. His book The Potter’s Promise has influenced many against Calvinism. An overview of Flowers’s theology is given in this book, chapter by chapter, and is exposed as an erroneous view of salvation. In these chapters the reader gets a historical overview of Calvinist thought. The reader will see how it is free-will theology that can be associated more with a heretical Gnostic ideology called Manichaeism as well as works-based Pelagianism. The various doctrines of Calvinism are supported from Scripture. This book also deals with common misrepresentations of Calvinism (i.e., that prayer is not necessary or that Calvinists don’t feel the need to evangelize) and provides the reader with a biblical basis for the several associated teachings of Calvinism in the appendix.
