In chapter four, The Christian Worldview, Groothius defines and delimits Christianity in order to properly defend it. Groothius thinks it is best to define Christianity according to its doctrines or its worldview. Groothius states that “a worldview is forged out of beliefs that have the most consequences for a comprehensive vision of reality…Our worldview shapes who we are and what we do. We are driven by our deepest beliefs and interpret the world according to them.”
