Obedience to God is an interesting thought. I think for most of us we assume that if we go to church we are being obedient, if we read the bible we are being obedient, if we pray we are being obedient. I am pretty certain that we do not think that if we eat right then we are being obedient.
I had a realization last night and that was that eating right and healthy is being obedient to God. Here is the deal. I have an addition to food and when you have an addiction to food it can consume your life. Anytime I allow something to consume my life that isn't God I am not being obedient. Therefore, in my life obedience to God means eating healthy.
