"Christianity’s answer to the question of why creation is so beautiful is that it flows from the character of a beautiful creator. Nature is God’s self-portrait. It is not God, since God transcends what He has created, but it reveals in physical form what He is like spiritually. God creates beauty so we can know what He is like. Since He is and always has been glorious and beautiful, creation reflects this with seeable, tastable, touchable, hearable, and smellable reflections of His glory and beauty. This is what Isaiah heard the angels exulting. The whole earth is filled with His glory, and it is a ‘song about God."
