C.S. Lewis quotes Blaise Pascal in his Introductory to The Problem of Pain. Says Pascal:
I wonder at the hardihood with which such persons undertake to talk about God. In a treatise addressed to infidels they begin with a chapter proving the existence of God from the works of Nature…this only gives their readers grounds for thinking that the proofs of our religion are very weak….It is a remarkable fact that no canonical writer has ever used Nature to prove God.
