The evangelist told him, "I am not preaching on gluttony tonight." The pastor told him, "well then you are not preaching tonight. Pack it up and move on." The evangelist was about 80 lbs overweight.
I personally do not drink. Having said that, I believe we should preach against sin; not simply pick and choose sins to preach about.
Just want to point out that people can be overweight - sometimes massively overweight - and it has nothing to do with gluttony or sin.
I was nearly 400 pounds less than a year ago and I didn't know why. For years, doctors and, I'll assume, well-meaning people informed me that I must be overeating and too lazy. I was not lazy and I knew I did not overeat. In fact, I tracked my calories and I consumed calories at a level where I should have been dropping weight very quickly.
After literally more than a decade of talking to doctors and getting nowhere, I diagnosed myself as likely having a pituitary disorder through the internet. A few weeks later I was at the doctor's office seeing a nurse practitioner for a cold and made my case. She had not had as much experience as other medical professionals I had seen and therefore didn't "know" that people with unusual disorders don't come into her office. She ordered a blood test to prove that I didn't have a problem. The test came back with unexpected results. I had more tests to prove I didn't have an issue. They came back with unexpected results. They ordered an MRI and found a pituitary tumor. I was then referred to an endocrinologist who assured me I didn't have a problem - I was just fat - and ran a test to demonstrate that I was a hypochondriac. That test came back positive. He ran a few more tests and finally diagnosed me with Cushing's Disease and referred me to a neurosurgeon. The neurosurgeon looked at me and told me I was just fat and decided that my test results and tumor may have just been the result of "being depressed" because I am so fat and my overeating. I showed him records of my diet and tried to persuade him to take me seriously - I had a diagnosis from an excellent endocrinologist! He refused to do anything about it, and Cushing's Disease can only be resolved through surgery - removing the tumor. Moreover, it will eventually kill you through complications.
I went to MD Anderson in Houston where a was completely reevaluated by a new endocrinologist and she determine that I did indeed have Cushing's Disease and I was still a good candidate for surgery - although I was rapidly getting worse. They performed surgery on 10/15/2015, and I am feeling much better today. I have also lost about 65 pounds since October and the weight is slowly coming off (about 10 pounds a month) without heavy dieting or excessive exercise.
However, I still face a fair amount of criticism about my weight from people who just assume things because of appearances. As a church leader, I stressed the importance of moderation and self-control, but many people could not get past my appearance and made assumptions about me that were false. That is incredibly frustrating when you are being faithful to God in those areas but being condemned for things out of your control.
I tell you all of this to make a point - do not judge people according to appearances. You may think it is obvious what is wrong, but there's a decent chance you really don't. Even among those who overeat, there are often some real and crippling issues that drive the overeating. You need to be concerned with those issues instead of simply claiming gluttony.
