Snow, an evangelical, wrote an article for Christianity Today in 2007 entitled Cancer's Unexpected Blessings. Here is an excerpt, the ending of his essay:
I sat by my best friend's bedside a few years ago as a wasting cancer took him away. He kept at his table a worn Bible and a 1928 edition of the Book of Common Prayer. A shattering grief disabled his family, many of his old friends, and at least one priest. Here was a humble and very good guy, someone who apologized when he winced with pain because he thought it made his guest uncomfortable. He retained his equanimity and good humor literally until his last conscious moment. "I'm going to try to beat [this cancer]," he told me several months before he died. "But if I don't, I'll see you on the other side."
His gift was to remind everyone around him that even though God doesn't promise us tomorrow, he does promise us eternity—filled with life and love we cannot comprehend—and that one can in the throes of sickness point the rest of us toward timeless truths that will help us weather future storms.
Through such trials, God bids us to choose: Do we believe, or do we not? Will we be bold enough to love, daring enough to serve, humble enough to submit, and strong enough to acknowledge our limitations? Can we surrender our concern in things that don't matter so that we might devote our remaining days to things that do?
