Richard Baxter, from The Reformed Pastor, chapter 1:
The most holy men are the most excellent students of God’s works, and none but the holy can rightly study them or know them. His works are great, sought out of all them that have pleasure therein,” but not for themselves, but for him that made them. Your study of physics and other sciences is not worth a rush, if it be not God that you seek after in them. To see and admire, to reverence and adore, to love and delight in God, as exhibited in his works—this is the true and only philosophy; the contrary is mere foolery, and is so called again and again by God himself. This is the sanctification of your studies, when they are devoted to God, and when He is the end, the object, and the life of them all.
