A biologist once told a story about his Harvard professor named Louis Agassiz, who taught him a simple habit to help him see more than he ever dreamed. The lesson he learned is also the secret to lifelong and life-changing Bible reading: keep looking.

One reason we see so little when we read the Bible is that we do not give ourselves long enough to look. John Piper shares the story “Agassiz and the Fish” in his new book Reading the Bible Supernaturally. In the seemingly ordinary act of reading the Bible, something miraculous happens: God gives us new eyes to see more of him — if we are willing to slow down and keep looking.
