One book, of course, is the Bible. The other is the book of nature. One of the most famous Reformation creeds, the Belgic Confession of 1566, makes the point: We know him [God] by two means: First, by the creation, preservation, and government of the universe, since that universe is before our eyes like a beautiful book in which all creatures, great and small, are as letters to make us ponder the invisible things of God: his eternal power and his divinity, as the apostle Paul says in Romans 1:20.[28]
