God's word illumines the darkness of society. Groen van Prinsterer's Unbelief and Revolution is a foundational work addressing the inherent tension between religion and modernity. As a historian and politician, Groen was intimately familiar with the growing divide between secular culture and the church in his time. Rather than embrace this division, these lectures, originally published in 1847, argue for a renewed interaction between the two spheres. Groen's work served as an inspiration for many contemporary theologians, and as a mentor to Abraham Kuyper, he had a profound impact on Kuyper's famous public theology. Harry Van Dyke, the original translator, reintroduces this vital contribution to our understanding of the relationship between religion and society.
