White House Press Secretary Tony Snow was profiled the other night on — ahem — some TV network. He spoke movingly about his battle with cancer. But it turns out he also wrote about it a few weeks ago, in this excellent piece for Christianity Today:

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.

There’s nothing wilder than a life of humble virtue—for it is through selflessness and service that God wrings from our bodies and spirits the most we ever could give, the most we ever could offer, and the most we ever could do.

Finally, we can let love change everything. When Jesus was faced with the prospect of crucifixion, he grieved not for himself, but for us. He cried for Jerusalem before entering the holy city. From the Cross, he took on the cumulative burden of human sin and weakness, and begged for forgiveness on our behalf.

We get repeated chances to learn that life is not about us—that we acquire purpose and satisfaction by sharing in God’s love for others. Sickness gets us partway there. It reminds us of our limitations and dependence. But it also gives us a chance to serve the healthy. A minister friend of mine observes that people suffering grave afflictions often acquire the faith of two people, while loved ones accept the burden of two people’s worries and fears.

Most of us have watched friends as they drifted toward God’s arms not with resignation, but with peace and hope. In so doing, they have taught us not how to die, but how to live. They have emulated Christ by transmitting the power and authority of love.

Read the whole thing. Really. It’s a superb meditation on life, love and faith.

Tony Snow has a great book inside of him, just waiting to be written. Let’s hope and pray he does it, and soon.
