To many Christians theology is something alien, overly intellectual and wholly unappealing. Even seminary students are known to balk at the prospect of a course on theology. Yet theology--most simply, the knowledge of God--is essential to the life and health of the church.In this short introduction, Stanley Grenz and Roger Olson, two theologians who care deeply about the witness of ordinary Christians and the ministry of the church, show what theology is, what tools theology uses, why every believer (advanced degrees or not) is a theologian and how the theological enterprise can be productive and satisfying. Their clear, easily understood book is ideal for students, church study groups and individual Christians who want to strengthen understanding, belief and commitment by coming to know God more fully.
