This approach leads only as far as deism and never to the God of Christian experience. Christianity is superior to a purely naturalistic inquiry because it takes account of historical events. Natural science deals best with generals. The function of natural theology is to challenge our common sense, our religious, experience. The subject matter of natural theology is divergent, whereas that of natural science is convergent.
Natural theology can falsify theological models.
The end of natural theology is not to establish or prove the existence of God. A fundamental insight of natural theology is that there is more to God than his dealings with humanity. This lecture was delivered on 16 September 1996.
