Theology is to life what a map is to a journey. Michael Gowens believes that every Christian should be a systematic theologian. Each should be able to formulate the core truths of the Bible in an orderly arrangement. It is not enough to simply store bits and pieces of Bible trivia about various subjects, or to simply derive comfort from selected passages of Scripture. A truly robust discipleship is the product of a mind that thinks theologically. Doctrine is vital.
