Jordan Rubin, author of The Great Physician's Rx for Health and Wellness, tells how he is often asked the question, "Can I get to Heaven eating unhealthy food?" He smiles and tells them, "Sure you will, you'll just get there a lot sooner."
I believe eating is one of those very personal things that each of us must decide for himself. Although God gives us guidance in His Word, I don't believe that our diets are necessarily a moral issue. There can be exceptions, of course. That is why this is one of those things that is between you and God.
Though I can't give you any hard and fast "rules" about if God cares what we eat, I can give you these facts:
Fact #1: He cares for you.
At one point in my life, I sold home decor items. One of our trademark pieces was a pottery dish that had the creator's fingerprints pressed into the handle so no two pieces were exactly alike. This is how God has created us. Each of us is unique, has our own special ministry and has God's own fingerprints upon our lives.
Fact #2: He cares about your health.
The reason God addresses food in the Bible at all is He loves us and wants what is best for us. He wanted His chosen people, the Israelites, to experience good physical health as He led them toward the Promised Land. He didn't want them to contract any of the diseases with which the Egyptians were plagued. There is no legalistic rule here....just pure love from our Heavenly Father.
Fact #3: He cares enough not to overwhelm us.
God's Word tells us that His yoke is easy and His burden is light. He never intended for any of His commands to be grievous to us. If you are overwhelmed by your attempt to eat healthier, perhaps you need to recognize that God is not requiring so much of you. Ask Him for wisdom and strength, and He will give it to you liberally.
Does God care what we eat? He cares much more than you know!
