"We were made to know and treasure the glory of God above all things; and when we trade that treasure for images, everything is disordered... what could be more ludicrous in a vast and glorious universe like this than a human being, on the speck called earth, standing in front of a mirror trying to find significance in his own self-image?" ~John Piper, Seeing and Savoring Jesus Christ
