I'll admit something. For years, I pictured the Christian race as a Sunday-afternoon jog. I saw myself in cute sneakers with a gentle breeze in my hair, waving at the neighbors and admiring the scenery. "It's a marathon, not a sprint," I'd say, as if a marathon were just a sprint with better snacks.

Then I looked up the Greek word for "race" in Hebrews 12:1, and my smoothie hit the pavement.

The word is agōn, and yes, it's where we get "agony." It was the word for the contests held in the great stadiums, where athletes strained, gasped, and gave everything they had. The word carries the idea of struggle and conflict. Nobody in that arena was admiring the scenery.

We love the race verse. We put it on mugs and bookmarks. But we rarely talk about what it's like to run it on mile nineteen, with a blister, a headache, and a to-do list that's grown legs.
