Proverbs 4:22 (NKJV) — 22 For they are life to those who find them, And health to all their flesh.
Words of life and health. The words of wisdom are more than mere human words. They possess life. They produce health in those who digest them. Instead of a vitamin deficiency, some people have a Word deficiency.
John 6:63 (NKJV) — 63 It is the Spirit who gives life; the flesh profits nothing. The words that I speak to you are spirit, and they are life.
