Perfect as a textbook yet excellent for lay readers, this updated edition builds a positive case for Christianity by applying the latest thought to core theological themes. J. Gresham Machen once said, “False ideas are the greatest obstacles to the reception of the gospel”—which makes apologetics that much more important. Wanting to engage not just academics and pastors but Christian laypeople and seekers, William Lane Craig has revised and updated key sections in this third edition of his classic text to reflect the latest work in astrophysics, philosophy, probability calculus, the arguments for the existence of God, and Reformed epistemology. His approach—that of positive apologetics—gives careful attention to crucial questions and concerns, including: the relationship of faith and reason, the existence of God, the problems of historical knowledge and miracles, the personal claims of Christ, and the historicity of the resurrection of Jesus. He shows that there is good reason to think Christianity is true. As Craig says, “If you have a sound and persuasive case for Christianity, you don’t have to become an expert in comparative religions and Christian cults. A positive justification of the Christian faith automatically overwhelms all competing world views lacking an equally strong case.”
