Tre is a regular at the fitness center and it shows. His shoulders are wide, his muscles pronounced, and his upper arms close to the size of my thighs. His physical condition prompted me to engage him in a spiritual conversation. I asked him if his commitment to physical fitness in some way mirrored a healthy relationship with God. Though we didn’t go too deep, Tre did acknowledge “God in his life.” We talked long enough for him to show me a picture of the four-hundred-pound, unfit, unhealthy version of himself. A change in his lifestyle had worked wonders physically.

In 1 Timothy 4:6-10, physical and spiritual training come into focus. “Train yourself to be godly. For physical training is of some value, but godliness has value for all things, holding promise for both the present life and the life to come” (vv. 7-8). One’s external fitness doesn’t change our status with God. Our spiritual fitness is a matter of the heart. It begins with a decision to believe in Jesus, through whom we receive forgiveness. From that point, training for godly living begins. This includes being “nourished on the truths of the faith and of . . . good teaching” (v. 6) and, by God’s strength, living a life that honors our heavenly Father.
