The holy word of HaShem brought the universe into existence, as per the morning prayer,"Blessed is He, Who spoke and the world came into being." Indeed, HaShem continuously issues good words and pleasant favors upon His creations. The gift of life, the joy of family and friends, the wisdom of the holy Torah, the wonder of health and intelligence all come to us through the good blessings of our Merciful Creator.
The faculty of speech, when properly used, has the power to impart life, beauty, blessing, and goodness.
Emulate HaShem by always speaking good words, positive linguistics, and share Torah ideas. Flow with gracious, complimentary, and encouraging words, and never let a negative or harsh word escape your lips.
