Christians are often torn between two opposing views: either to dominate the world in God's name or to retreat into isolated communities of counter-cultural witness. In his book, Why You're Here, John Stackhouse presents a balanced and practical approach, rooted in Scripture, that navigates this dilemma. He explores the meaning of human existence in this life and the next, offering a clear and achievable program for faithful Christian living. This accessible guide is designed for everyday Christians seeking straightforward answers to complex questions and struggling to stay true to biblical teachings amidst ambiguity, irony, and difficult choices. From politicians and medical professionals to businesspeople, professors, lawyers, pastors, students, and all those concerned with realistic and hopeful Christian engagement, Why You're Here provides a framework to inform and inspire daily life. By embracing this vision, Christians can live with purpose, integrity, and confidence in today's complex world.
