Here, L'Engle explains how ordinary things such as family, words, the Bible, heaven, and even penguins can become such windows. She also shows how such a window becomes an idol-a penguin becomes a "golden calf"-when we see it as a reflection of itself instead of God.

With delightful language, insightful metaphor, and personal stories, L'Engle brings readers to a deeper understanding of themselves, their faith, and the presence of God in their daily lives.
