The answer is: By the fruit of his mouth

Pro 18:20

Proverbs 18:20 presents us with a little gem packed with wisdom! "A man's belly shall be satisfied by the fruit of his mouth" means that the words we speak and the conversations we engage in have a direct impact on our satisfaction and fulfillment in life. It’s a colorful metaphor: just as our physical hunger is fulfilled by food, our emotional and social needs are often satisfied by the relationships and communication we nurture.

This notion reflects a timeless truth — our words can build bridges or tunnel us in isolation. Have you ever noticed how sharing a good laugh with friends can immensely lighten your mood? Proverbs encourages entertaining conversations as a source of nourishment for our spirit. It's no wonder that in many cultures, gathering over a meal is an age-old tradition filled with robust discussions!

Interestingly, this intelligible insight echoes throughout scriptures. In Matthew 12:34, it says, "Out of the abundance of the heart, the mouth speaks," reinforcing the importance of sincere and kind speech. Think about how one thoughtful conversation can transform your perspective or renew your spirit. It’s as if each word we share has a life of its own.

Moreover, the idea helps us understand why speaking with kindness and integrity not only pleases others but also fills our own 'belly' with happiness and contentment. Words are powerful tools — they can uplift, inspire, and satisfy, when used wisely!
