There are foods that honor God’s temple and foods that do not honor it. We would not throw trash inside the sanctuary where we worship, nor should we put things in our bodily temple that do not belong in it. We consume things that do not belong in the body because we like how they taste and we mistakenly believe that they are good for us.
When we consume junk foods such as potato chips, donuts, soft drinks, snack cakes, etc., we are trashing our temple. These are poisonous substances, not foods, because they are completely void of nutrients and we consume them exclusively for their taste. The offense against our temple is blatant and egregious. These are terrible addictions that must end if we want to truly honor the temple that God has given us.
For if you live according to the sinful nature,
you will die; but if by the Spirit you put to death
the misdeeds of the body, you will live.
Romans 8:13 [NIV]
