Some brilliant quotes from the video:
Quoting Pope John Paul II, Great art makes us nostalgic for God.
That universal desire for redemption, when you touch that place in the human heart, that's heartbreaking in the best sense of the word.
More and more and more, the gaps of time between when you last saw Jesus and some moment...the gap just gets shorter and shorter until finally all you see is God.
I discuss in Creative Theology the idea that beauty causes us to long for the Creator. Nature and art and stir something in us that longs for the Garden, immersed in beauty and in communion with God. It's heartbreaking, like Ian says, in the best sense of the word.
