The world needs your faithful influence We live in a complex world, and confrontations between competing worldviews and value systems are common. The great challenge for the Christian is how to impact this fallen world with our faith. To have the greatest influence on someone who doesn't share our belief system, we have to start with knowing what they believe, why they believe it, and how that belief affects their attitudes, behaviors, and choices. In Making a Difference, beloved theologian R. C. Sproul shows you 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 we 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 your faithful influence today: economics, science, art and literature, and government. If you long to make a real and lasting difference in your family, friend group, workplace, and community, this book will show you how.
