Whatever you think of Tony Snow's politics, read where he shares what he has learned battling cancer. What a challenge for us! And what an encouragement as some within our church battle this disease. 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.
