Thanks a lot for contributing to my reputation in town as “that idiot who laughs while jogging.” (Oliver Edwards, a runner)
How often do you see a runner smiling, much less laughing, while he or she is doing their daily workouts? Some of us don’t run (or exercise) because it isn’t fun and may include some aches and pains. But the benefits of regular exercise are most often far greater than the occasional ache (or ridicule as in Edwards’ case). Spiritual exercise is even more beneficial.
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 (1 Timothy 4:8).
