I love cake! But, when I start letting myself eat it, my appetite for sugar spirals out of control. One thing leads to another and before I know it, I've added ten pounds, I become sluggish, and tired. The extra weight makes my clothes fit tight and I'm uncomfortable. Why do I do this to myself? I know all this happens every time I go on a sugar binge, and yet I continue. Is that a sin for me? Maybe gluttony. I certainly need to consider it a sin for myself! We all have weaknesses and we know what they are, but what should we do about them? It takes so much courage and self control to refrain from indulging in unhealthy behavior. So, whether it's lust of the flesh or lust of sugar, or whatever has control of you, you must work diligently to give it up. We should allow nothing to rule over us except the Holy Spirit. This is an ongoing process. You may give one thing up, but then another thing pops up. It's a matter of recognizing it before it becomes your god.
But I discipline my body and keep it under control, lest after preaching to others I myself should be disqualified. 1 Corinthians 9:27
