It should be easy for Christians to understand what needs to be done.
This world that God has made is both intricate and beautiful on any scale we choose. No matter how small, or large, it is a work of art, delicate in beauty, elegant in majesty, without compare. Observe the beauty of the Forest, a Tree, a Leaf, a single cell of that Leaf.
Now imagine, when you have died and gone to meet your Maker, that you are greeted at the Gate by a certain Mr. Da Vinci, a Painter, and you are needing to explain why you felt it was alright for you and your family to use pieces of the Mona Lisa to wipe your ass.
