" Worthless talk can also contribute to conflict, even if you intend no harm. It violates God’s high standard for talking to or about others: “Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen” (Eph. 4:29). Worthless talk also shows a disregard for Jesus’ warning, “But I tell you that men will have to give account on the day of judgment for every careless word they have spoken” (Matt. 12:36). If you memorize these passages and use them consciously as a filter for your words, it can help you to avoid many kinds of careless, critical, worthless words and to speak only those things that will benefit others, build them up, and promote spiritual growth.1 "
