His first book, The Origin of Paul's Religion (1921) was a masterful and forthright defense of the historical truthfulness and supernaturalism of the New Testament. This volume is taken from the James Sprunt Lectures delivered at Union Theological Seminary in Virginia. Machen is absolutely masterful in dealing with the anti-supernaturalism that was beginning to dominate the church in the early decades of the twentieth century. Although written 85 years ago it remains a model of biblical scholarship and warm piety.
