The temporary nature of life often leaves us with questions and unresolved tension in our souls—both when we contemplate dying and when those we care about pass on to eternity. But Calvin Miller’s Letters to Heaven is about more than leaving earth; it is about how much living is learned from those who have died. The legacy of the people who have left us is “a pearl of great worth”; wherever we have encountered giants of thought or champions of the heart, prominent pastors or innocent children, unwitting saints or long-suffering mothers, we can gather exceeding value from the scenes of their lives. Their hope can become our hope. Their courage can become our courage. We can stand strong because so many are willing to lend us their strength, if only we will take the time to let them.
