Challenging the dominant Van Tillian approach in Reformed apologetics, this book by a leading expert in contemporary Reformed theology sets forth the principles that undergird a classic Reformed approach. J. V. Fesko's detailed exegetical, theological, and historical argument takes as its starting point the classical Reformed understanding of the two books of God's revelation: nature and Scripture. Believers should always rest on the authority of Scripture but also can and should appeal to the book of nature in the apologetic task.
