Death and Life are in the Power of the Tongue

I love how the bible uses language from the earth to describe deep spiritual truths. We've lost a lot of understand as many of us no longer work outside but consider the below excerpts from the Proverbs 18:

Proverb 18:
"4 The words of a man's mouth are deep waters;
    the fountain of wisdom is a bubbling brook."

"21 Death and life are in the power of the tongue,
    and those who love it will eat its fruits."

A "bubbling brook" sustains life in a desolate land just as loving words can water a parched soul. This "water" also helps to grow the fruit of the soul. Hateful words grow bitter fruit and loving words grow sweet fruit. Thus, out of the abundance of the heart the mouth speaks, but the corollary is also true: From the desire of the heart the ear receives.
