I receive health food, supplement, and exercise information on a regular basis. I do this because I realize that there are benefits to eating and doing the right things for my physical body. But there are those in the health-conscious world who think that this alone is how to have a long, healthy, happy life. They are sadly mistaken.
Here in Proverbs 9 we have wisdom personified telling us that the fear of the Lord is the beginning of wisdom - and that the knowledge of the Holy One is the way to live with understanding in this world. Immediately after that statement wisdom then tells us that He is the One who can add to our days and give us a long, happy life. It is wisdom that mattters - and God is the One who can give it to us.
While I do agree that certain health-conscious choices will lengthen our days - none of the sage advice of the health guru's has anything on the revelation of God in the Scripture. When you look at the Old Testament laws concerning food and cleanliness, you realize that within that system that is nearly 4000 years old is the best way to stay healthy and free from disease. It is really shocking to some when they realize this. I mean, these folks didn't even have hand sanitizer!
God's Word goes far beyond just physical well-being though. It moves into the area of spiritual well-being. That involves far more than just sitting on a floor chanting and centering yourself in . . . yourself. It involves being in a right relationship with God. It is moving all your temporary, momentary physical health toward what God intended for you in the first place - to know, serve, and love Him. If we are not doing this - it really doesn't matter how many "pain-free" and "vital" years we live on this earth. Things WILL go badly for us the moment we die. So, may God give us wisdom to follow Him . . . in what is best for us physically, and what is best for us spiritually. That is the way to a long, healthy, wonderful life here on earth - and a life after your days here are ended - that will last throughout all eternity.
