According to wise old king Solomon, our eyes are never satisfied.1 This statement extends beyond beyond food, but food is a bit of a softball when it comes to applying Solomon’s words. If there’s room on the plate, then there is room for more food, right? I’d like to make the quick case that being weak in handling food/fitness can lead to weakness in other areas of life. Very simply, if we cannot buffet the body regarding food /fitness, we’ll find it an uphill climb with other desires of the flesh.
Obedience and discipline aren’t on a switch we can turn on / off depending on the current moment. In other words, I can’t be strong against lust when I eat whatever is in my sightline. I cannot contend well with anger when I contend poorly with overall bodily fitness. If I am soft when it comes to my mouth, I’ll be weak in other areas where the flesh is demanding. Weakness in one area equals weakness in more than one area. Thomas Boston once said, “They that would keep themselves pure must have their bodies in subjection, and that may require, in some cases, a holy violence.”
Basically, being soft in our bodies inclines us towards weakness and softness in our spiritual lives as well. Bodily weakness is contagious. I’m not making this up, but ripping it off from the Apostle Paul. Speaking to a church that struggled with the flesh out loud for all to see. “Every athlete exercises self-control in all things...So I do not run aimlessly; I do not box as one beating the air. But I discipline my body and keep it under control, lest after preaching to others I myself should be disqualified.”2
Paul is connecting the discipline he applies to the exterior man with the result in the inner man. He knew that being weak in discipline regarding his physical body will without a doubt drive towards spiritual weakness and possibly disqualification. Jerry Bridges agrees with Paul:
“When the body is pampered and indulged, the instincts and passions of the body tend to get the upper hand and dominate our thoughts and actions. We tend to do not what we should do, but what we want to do, as we follow the cravings of our sinful nature.”3
Andrew Murray more bluntly says, “Overeating or eating for mere enjoyment, weights and makes the body heavy and unfit for prayer. That is the time the devil can come to you. A man may be living in victory over some sin but through the pleasure of eating the devil may get power over his flesh.”4
How we handle food and fitness is not an amoral issue outside of how we engage God, but a vital part of who we are as worshipers and disciples of Jesus. When strategy and discipline launch from this footing, it’s worshiping God. When discipline derives from what culture deems “beautiful” however it’s self-worship. This is why you can be fit and healthy and yet be in sin of self-worship. Step one is seeing weakness over your own body as a moral problem. Step two is developing a strategy for God’s honor, not your own.
