The Language of Mathematics
Math, unlike other natural laws, is abstract. That means it's not attached to anything. Is the same everywhere in the universe. Some laws of physics for example change from place to place, but not the laws of mathematics. So, if God had created a different universe, while other things might be different, Mathematical Laws would be the same. If that's true, then math is a Transcendent Truth, it exists outside of the universe and creation. It must be a part of God's language, the way He communicates with us. When you see patterns in nature (Fibonacci sequence in flowers, etc.), hear the music of nature, move, find yourself following a pattern or rhythm (seasons, breathing) God is speaking to you. He's communicating through a language that is so fundamental and exquisite.
I've been thinking about this a lot lately, and how the beauty of nature moves us, how music has such captivating power, how math is so much more than numbers. We were watching a movie last night and they quoted Galileo, "The laws of nature are written by the hand of God in the language of mathematics." Beautiful.
