I came across this verse while studying something else:
Woe unto you, scribes and Pharisees, hypocrites! for ye make clean the outside of the cup and of the platter, but within they are full of extortion and excess. Matthew 23:25
One of the sins of the Pharisees was that they were "full of excess." How convicting to one with a lot of excess weight!
Yet it is helpful, too. One of my struggles is that, unlike a smoker or alcoholic, we can't just put away what we indulge in. We do have to eat. And it depresses me to think of never eating a cookie or burger again. But if I keep in mind that excessiveness, either of the amounts or the wrong types of foods, is the problem, I think that helps me get my mind around handling it.
