Christian who is becoming a psychologist or psychiatrist. When I write of the scope of special revelation, I am referring to the thorny problem captured in this simple question: For how many of humanity’s disorders are we given clear and exhaustive guidance in Scripture for their resolution? How do we understand the scope of special revelation with regard to human ills? By way of analogy, the knowledge of how to extend life by fabricating insulin and administering it to diabetics is a great good.
