It is a significant selection of people to whom the poignant messages in Calvin Miller’s Letters to Heaven are addressed. Among the recipients are heroes and martyrs, mentors and authors. Some were very well-known to Miller, and others were strangers who influenced him in lasting ways. Some were household names and others were quiet saints. Each one yielded a valuable lesson, whether the experience from which that lesson came was made up of years or only a hour. The lives of these long-absent people stand out like flares in the darkening landscape of mortality, their thought-provoking words and actions still lighting up the land of the living.
