For people to see the character of God from us, God must dwell inside of us. Thus we strive to keep our bodies holy and teach the importance of health living. With God dwelling in us, Satan does not stand a chance and must flee. Also, a health walk with Jesus is an enjoyable and happy life.
16 Know ye not that ye are the temple of God, and [that] the Spirit of God dwelleth in you? 17 If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which [temple] ye are.18 Let no man deceive himself. If any man among you seemeth to be wise in this world, let him become a fool, that he may be wise. 19 For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness. 20 And again, The Lord knoweth the thoughts of the wise, that they are vain. 1 Corinthians 3:16-20
