This verse really stuck out to me. I am a latter-day saint, and our prophet Thomas S. Monson once said something very similar. He told us not to use harsh words in one of his many speeches. This particularly rings a note for me, because after I sobered up I was given promptings from Heavenly Father to quit using certain words. I wasn't sure what all the reasons were, but I obeyed. Now, I have much more context and a great amount more understanding as to the why I should watch my mouth and safeguard my tongue. This all also reminds me of the Epistle of Saint James, wherein said James asks that we mind our tongues and similar such things as this. The Mazdaasnians, also known as the Zoroastrians, have long minded their language, based on the teaching of their prophet Zarathushtra (Zoroaster). I can testify that we will receive many blessings after we have continued to keep our words clean. In Christ's name; amen.
