The great challenge for the Christian in a post-Christian context is how to impact this fallen world with our faith. In Making a Difference: Impacting Culture And Society As A Christian, beloved theologian R. C. Sproul shows readers how to confront today's moral and social issues with an effective biblical response. Dr. Sproul first examines the major philosophies that affect the way Americans think and act--secularism, existentialism, humanism, and pragmatism--and then presents ideas on how to apply a biblical perspective to spheres of public life that need the Christian's influence today: economics, science, art and literature, and government.
