Saint Augustine:
"What is that I love in loving You? Not physical beauty, not the splendor of time. It's not the radiance of the light, which is so pleasant to our eyes, or the sweet melodies of various kinds of music. Nor is the fragrant smell of flowers and ointments and spices, it's not manna and honey or the limbs embraced in physical love. It's not these that I love when I love You, my God.
Nevertheless, it's true that I love a certain kind of light and sound, fragrance and food, and embrace in loving my God. For You are the light and sound and fragrance and food and embracement of my inner man. You are the light that shines into my soul which no physical place can contain, where time does not snatch away the lovely sound, where no breeze disperses the sweet fragrance, where no eating diminishes the food, and where there is an embrace that can't be torn asunder. This is what I love when I love my God.
What is this God? I asked the earth, and it answered, " I am not He." Everything in the earth made the same confession. I asked the sea and the deeps and the creeping things, and they replied, "We are not your God; seek above us." I asked the heavens, the sun, the moon, and the stars; and they answered, " Neither are we the God whom you seek."  
I replied to all these things that surround me: " You have told me about my God, that you are not He. Tell me something about Him" With a loud voice they all cried out, "He made us." My question had come from observing them, and their reply came from their beauty of order.
I then turned my thoughts inward to myself and said, "who are You?"...
