Both inside and outside the Christian faith, many difficult realities trouble human hearts and minds. By being equipped to answer questions about suffering and evil, Christians can persevere in faith, share their faith, and defend the faith when confronted with these inevitable challenges of living in a fallen world. In 40 Questions About Suffering and Evil, Greg Welty shows the necessity of exploring our vocabulary around evil and suffering so we can clearly see and express the best questions. Welty explores vital ideas, backgrounds, and issues.

Calvinism and Middle Knowledge is an anthology of essays that moves the discussion of Molinism/middle knowledge out of the philosophical arena, where it has almost exclusively remained, and into the broader theological community. In particular, it sparks a conversation between Calvinists and Molinists regarding the fruitfulness or deficiencies of middle knowledge and the feasibility or infeasibility of Calvinist use of middle knowledge without acceptance of libertarian human freedom. To this end, nine distinguished experts address such topics as the history of the doctrine of middle knowledge, the potential role of Molinism in discussions of evolution and intelligent design, Calvinist concerns with Molinism, and Calvinist appropriation of middle knowledge.

Alvin Plantinga is the contemporary world’s most influential Christian philosopher. His work over the past six decades has paved the way for Christian thinkers in the fields of philosophy of religion, epistemology, metaphysics, and science. Despite the widespread rejection of Christian assumptions by the majority of modern thinkers, Plantinga is unembarrassed to use them in his academic work and defends them well.

Great Thinkers is an academically, biblically, and theologically informed series that explores the seminal thoughts of leading philosophers who have shaped the modern world. Writing from a Reformed perspective, the authors in the series identify the most influential cultural features of each great thinker and the most apologetically effective ways to address these.

The 40 Questions series is written to assist faithful Christians in making God-honoring decisions in the life of the church, biblical studies, theology, and other areas. Authors write from a wealth of practical experience and assist readers in avoiding common ministry mistakes.

Many people argue that the presence of evil in the world is proof that God cannot exist, or if He does exist, cannot be good or all-powerful. Greg Welty uses biblical exegesis alongside his experience as a philosopher to present a different conclusion. God, the sovereign Creator and Sustainer of the world, really does work all things for good. A must-read for anyone struggling with this issue.
