“There is no such thing as a separate natural theology that could be obtained apart from revelation solely on the basis of a reflective consideration of the universe. The knowledge of God that is gathered up in so-called natural theology is not the product of human reason.
“Rather, natural theology presupposes, first of all, that God reveals himself in his handiwork. It is not humans who seek God but God who seeks humans, also by means of his works in nature.
“That being the case, it further presupposes that it is not humans who, by the light of natural reason, understand and know this revelation of God. Although all pagan religions are positive [concrete], what is needed on the human side is a mind that has been sanctified and eyes that have been opened in order to be able to see God, the true and living God, in his creatures.
“And even this is not enough. Even Christian believers would not be able to understand God’s revelation in nature and reproduce it accurately had not God himself described in his Word how he revealed himself and what he revealed of himself in the universe as a whole.
“The natural knowledge of God is incorporated and set forth at length in Scripture itself. Accordingly, Christians follow a completely mistaken method [sic!] when, in treating natural theology, they, as it were, divest themselves of God’s special revelation in Scripture and the illumination of the Holy Spirit, discuss it apart from any Christian presuppositions, and then move on to special revelation.
