Third, we can open our eyes and hearts. God relishes surprise. We want lives of simple, predictable ease—smooth, even trails as far as the eye can see—but God likes to go off-road. He provokes us with twists and turns. He places us in predicaments that seem to defy our endurance and comprehension—and yet don't. By his love and grace, we persevere. The challenges that make our hearts leap and stomachs churn invariably strengthen our faith and grant measures of wisdom and joy we would not experience otherwise.

The moment you enter the Valley of the Shadow of Death, things change. You discover that Christianity is not something doughy, passive, pious, and soft. Faith may be the substance of things hoped for, the evidence of things not seen. But it also draws you into a world shorn of fearful caution. The life of belief teems with thrills, boldness, danger, shocks, reversals, triumphs, and epiphanies. Think of Paul, traipsing though the known world and contemplating trips to what must have seemed the antipodes (Spain), shaking the dust from his sandals, worrying not about the morrow, but only about the moment.

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.
