What does the Bible say about a person who has excess weight? Would the Bible say something about an overweight person who is a glutton and slothful; are they any more sinful if the person has an eating disorder like a binge eating disorder? I am assuming that a person who is Baptist would have a different position on this than say a Catholic or Methodist. I am overweight and though I suspect I have a binge eating issue, will I be judged about it? Or is being overweight a sin anyway?
There are many reasons for why a person is over weight, and overeating is just one of them. Eating the wrong type of food is another. We are hemmed in by advertisements for fast food, and for someone who hasn't the time to cook, getting KFC or McDonalds is a convenient alternative. Many have no idea about nutrition and therefore have unbalanced diets. Weight gain happens silently, stealthily and over a long period of time. Then to try and take it off is a difficult, challenging process.
We need to remember that Jesus said it was not what goes into a person that defiles them, but what comes out in the form of anger, riotous living, criticism, backbiting, gossip, accusative comments, hatred, spiritual abuse, etc, etc.
Boredom, lack of purpose, and depression are major causes for a person becoming over weight. They use comfort food as an anesthetic, in the same way another person uses alcohol or drugs for the same purpose. So, to deal with the surface presenting problem, one must get down to the underlying issues that give rise to it.
The answer for a Christian is to close with Christ and develop an intimate personal relationship with Him. Then the person develops into the person that Jesus wants him or her to be. As the person moves into the standing with Christ where he or she should be and starts to know it, then their mind is being transformed to a style of thinking that is conforming to Christ. As that happens, old habits and presenting problems fall away, because inner healing takes place, and the need for comfort food drops away and the person adopts sensible eating patterns and habits.
This is a lifestyle change brought about by the healing work of the Holy Spirit in the person's spirit, soul and mind. Therefore, the answer is to start from the inside - Christ within working the solution from the inside to the outside. Man looks on the outward appearance, but God looks on the heart. Man tries to solve the problem from the surface. God works on the problem starting with the heart.
Condemning and criticising a person and accusing them of gluttony is using man's wisdom instead of God's truth. The devil loves it because he is the accuser and those who accuse others work in total unity with him to drag down and destroy a believer's faith in Christ. Jesus does the opposite. He works within the believer to strengthen faith, confidence and trust in Him, and through that, the surface problems begin to be resolved.
