Today's Quote: Observe Silence and Refrain from Idle Talk

How can we use the following exhortations to improve our characters and our marriages?
"He [the true seeker] must never seek to exalt himself above anyone, must wash away from the tablet of his heart every trace of pride and vain-glory, must cling unto patience and resignation, observe silence and refrain from idle talk. For the tongue is a smoldering fire, and excess of speech a deadly poison. Material fire consumeth the body, whereas the fire of the tongue devoureth both heart and soul." - Baha'u'llah

"But I say unto you, that every idle word that men shall speak, they shall give account thereof in the day of judgement." - Matthew 12:36
