At the beginning of the twentieth century, famed theologian Abraham Kuyper toured the Mediterranean world and encountered Islam for the first time. Part travelogue, part cultural critique, On Islam presents a European imperialist seeing firsthand the damage colonialism had caused and the value of a religion he had never truly understood. Here, Kuyper's doctrine of common grace shines as he displays a nuanced and respectful understanding of the Muslim world. Though an ardent Calvinist, Kuyper still knew that God's grace is expressed to unbelievers. Kuyper saw Islam as a culture and religion with much to offer the West, but also as a threat to the gospel of Jesus Christ. Here he expresses a balanced view of early twentieth-century Islam that demands attention from the majority world today as well. Essays by prominent scholars bookend the volume, showing the relevance of these teachings in our time.
