What we say reveal our heart.
What we say and how we say it is who we are. Angry, hurtful words define an angry, hurtful person. Kind, compassionate words define a kind, considerate person (Chofetz Chaim, page xxi) But more than anything, words are the sole medium through which the Jew fulfills the purpose for which he was created – to communicate Hashem’s greatness and presence in this world. (page xxii)
Today is understood to be the first day of Creation that God said “Light Be!”. This brought the creating Spirit presence back into the earth. We also are created to create with our words.
This 40 days of Turning Back to God (Teshuvah), the most important thing we can do is judge everything we say according to the royal law of love. I Cor 13:4-7, everything. But don’t walk around not saying anything, speak praises unto God where ever you are, bringing light into this dark world.
