From Albert M. Wolters' Creation Regained, pp. 34-35.

We must continue to try to discern, through empirical study and historical experience, what God's specific norms are for areas of human life that the Scriptures do not explicitly address--industrial relations, for example, or the mass media, or literary criticism.

To say this is not to downgrade the authority of Scripture. The recorded explanations are indispensable, not least as an invaluable corrective for those who have their own interpretations of the blueprint. In all disputes of interpretation, the architect's own explanation are  clearly the final authority. The point is that the explanations cannot be fully understood without the blueprint to which they refer, just as the blueprint is in turn largely unintelligible without the explanations. But it is inconceivable that the blueprint should ever be invoked against the architect's own verbal explanations of it. That would be insufferable arrogance on the part of the builder. 

 . . . In Christ we are journeyman builders--still bound to the architect's explicit directions, but with considerable freedom of implementation as new situations arise. 

From Albert M. Wolters' Creation Regained, pp. 37-38:

Creation is not something that, once made, remains a static quantity. There is, as it were, a growing up (though not in a biological sense), an unfolding of creation. This takes place through the task that people have been given of bringing to fruition the possibilities of development implicit in the work of God's hands. The given reality of the created order is such that it is possible to have schools and industry, printing and rocketry, needlepoint and chess. The creational law is crying out to be positivized in new and amazing ways. The whole vast range of human civilization is neither the spectacle of the arbitrary aberrations of an evolutionary freak nor the inspiring panorama of the creative achievements of the autonomous Self; it is rather a display of the marvelous wisdom of God in creation and the profound meaningfulness of our task in the world. We are called to participate in the ongoing creational work of God, to be God's helper in executing to the end the blueprint for his masterpiece.

From Albert M. Wolters' Creation Regained:

There is . . . a crucial difference between the laws of nature and norms. In speaking of the "stormy winds that do his bidding" (Ps. 148:8), the psalmist does not ascribe responsibility to the wind. The wind cannot help but obey. But human beings do have responsibility: we are held to account for the way we execute God's commandments, and we are liable to punishment if we do not execute them all. Norms are complex. They can be violated in any number of ways, and they also leave a good deal to the resourcefulness and responsible imagination of the human being who is called to implement them. The command "Be just" must be applied to many different and complex human situations, nor is it always easy to determine in any given situation what justice requires. Yet it is our uniquely human task to put into concrete practice the requirements of the norm for justice. A falling stone has no comparable task in obeying the law of gravity, nor does an eagle in observing God's ordinances for raising its young. The stone obeys necessarily, the eagle responds instinctively, but a person must exercise personal responsibility: we are called to positivize the norm, to apply it to specific situations in our lives. All of human life, in all its vast array of cultural, societal, and personal relationships, is normed in this sense. The almighty Creator lays claim to all; the universal Sovereign lays down his laws for it all; the absolute King requires his will to be discerned in it all.

From Albert M. Wolters' Creation Regained:

There are two ways in which God imposes his law on the cosmos, two ways in which his will is done on earth as in heaven. He does it either directly, without mediation, or indirectly, through the involvement of human responsibility. Just as a human sovereign does certain things himself, but gives orers to his subordinates for other things, so with God himself. He put the planets in their orbits, makes the seasons come and go at the proper time, makes seeds grow and animals reproduce, but entrusts to mankind the tasks of making tools, doing justice, producing art, and pursuing scholarship. In other words, God's rule of law is immediate in the nonhuman realm but mediate in culture and society. In the human realm men and women become coworkers with God; as creatures made in God's image they too have a kind of lordship over the earth, are God's viceroys in creation.
