Karl Barth said this quote
“ He has heard, and causes those with ears to hear, even today, what we shall not see until the end of time - the whole context of Providence. As though in the light of this end, he heard the harmony of creation to which the shadow belongs but in which the shadow is not darkness, deficiency is not defeat, trouble cannot degenerate into tragedy and infinite melancholy is ultimately forced to claim undisputed sway...Mozart causes us to hear that even on the latter side, and therefore in its totality creation praises its master and is therefore perfect. ”
