God writes the Gospel not in the Bible alone, but on trees and flowers and clouds and stars.

Men argue, nature acts.

A righteous man regardeth the life of his beast.

Drive out nature with a pitchfork, and she will always come back. 

We never are definitely right; we can only be sure we are wrong.

Nature’s rules have no exceptions.

A tree’s a tree. How many more do you need to look at?
