God is a constant teacher, even when we don’t remember that we are students; and lessons in life and faith can be found in the most unexpected places. What might Calvin Miller have expected to be taught on the night when a man died next to him on a flight to Memphis? What could he have hoped to learn from a perpetually joyful child who left for heaven much too soon? It is people like these, young and old, to whom Miller writes in Letters to Heaven. His words extend to close friends, but also to famous personalities such as C. S. Lewis, Johnny Cash and Farrah Fawcett. Each person is special in their own way, and Miller reveals their unique stamp on the human story, especially his story. Wherever we walk on the earth, our footprints make lasting impressions.
