From Albert Wolters Creation Regained:

"One of the unique characteristics of human beings is that we cannot do without the kind of orientation and guidance that a worldview gives. We need guidance because we are inescapably creatures with responsibility who by nature are incapable of holding purely arbitrary opinions or making entirely unprincipled decisions. We need some creed to live by, some map by which to chart our course. The need for a guiding perspective is basic to human life, perhaps more basic than food or sex." 

 "The Scriptures are many things to the Christian, but central to their purpose is instruction. There is no passage in Scripture that cannot teach us something about God and his relationship to us. We must approach the Scriptures as students. . . . 'Everything that was written in the past was written to teach us,' says Paul of the Old Testament Scriptures (Rom. 15:4), and the same applies to the New Testament. That is why the concept of 'sound doctrine' is so central in the apostolic witness--not doctrine in the sense of academic theology, but as practical instruction in the life-and-death realities of our walk in the covenant with God. . . . That is also involved in what Paul calls the 'renewal of our minds' (Rom. 12:2). We need that renewal if we are to discern what God's will is in the full range of our lives--'his good, pleasing and perfect will.'"
