Book excerpt: Pilgrim Theology is a map for Christians seeking to better understand the core beliefs of their faith. Even though it's the study of God, theology has a reputation for being dry, abstract, and irrelevant for daily living. But theology is a matter of life and death. It affects the way you think, the decisions you make, the way you relate to God and the world. Reformed theologian and professor Michael Horton wrote Pilgrim Theology as a more accessible companion to his award-winning systematic theology The Christian Faith: widely praised for its thorough treatment of the biblical and historical foundations of Christian doctrine. In Pilgrim Theology, his focus is in putting the study of theology into the daily drama of discipleship. Each chapter will orient you toward a clear understanding about: Who God is. What our relationship is to him. And what our faith in Jesus Christ means in our daily walk as well as in the context of the narrative of Scripture and the community of the church. Through accessible chapters on individual doctrines, as well as frequent "Key Distinction" boxes that succinctly explain the differences between important themes, you'll gain an understanding of doctrines that may have sounded like technical seminary terms to you before: justification, sanctification, glorification, union with Christ, and others. You have a working theology already—an existing understanding of God. It's the goal of Pilgrim Theology to help you examine that understanding more closely and have it challenged and strengthened.
