Invited to speak at the Stone Lectures at Princeton Theological Seminary in 1898, Kuyper took the opportunity to deliver this message on the importance of Calvinism as a comprehensive life-system, or what today we might refer to as a worldview. Kuyper is simply brilliant and his writing is amazing tackling difficult issues and concepts, yet making it accessible to an interested and engaged reader. Kuyper believed that God was (and is) interested in all facets of human life and that the belief-system of Christianity addressed all the various facets of human endeavor. Lectures on Calvinism begins with an overview of Calvinism as a Life-system and then is broken down into chapters that relate how Calvinism addresses religion, politics, science, art and the future.Kuyper addresses three primary spheres of human involvement (1) our relation to God, (2) our relation to man, and (3) our relation to the world. Kuyper believed that a proper understanding and perspective of these three spheres would give man a proper biblically-based relationship to God and others and that proper perspective was one of engagement for the cause of Christ, not monastic flight from the issues of the day.Avoidance of the world, according to Kuyper, is not biblical. But understanding how to engage and placing a proper emphasis on the importance of worldly things is also a must. For those who believe they have an understanding of Calvinism from the simplistic five points of Calvinism, this book would blow them away! The book is not for everyone I would suggest only a serious reader would enjoy this book but if well-read, this book is definitely worth the time and effort!
