Proverbs 4:22 For they are life unto those that find them, and health to all their flesh.
The words and sayings of wisdom are life and health. The conditional promises of getting, gaining, and keeping Wisdom continue. The command is: listen to my words and keep them in your heart. Read, listen, study, and pay attention to the Word of God; keep God’s words in the middle of your heart; ponder and meditate on the Law and the Gospel; receive the Law to know what to do and believe the Gospel to have the power to do it.
The promise is life and health. Good, genuine enjoyment of life and living, along with solid mental, emotional, spiritual, and physical health come to those who are “in the Word” and believe the Gospel daily. The Torah gives the right way to live; The Gospel gives the power to live that way. This is Wisdom. Wisdom promises life and health. A good life and good health are not automatic “rights” that we may demand; they are gifts and blessings received with faith and thanksgiving. Life and health are promises received based on the Word and Wisdom of God.
