Words can do grievous amounts of damage to someone, including our brothers and sisters in Christ. It's so easy to let loose means words, even if they hold truth. But worse than that, we can grieve even our Creator. Ephesians 4:30-32 records something beautiful, saying,
"Do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. Let all bitterness and wrath and anger and clamor and slander be put away from you, along with all malice. Be kind to one another, tender-hearted, forgiving each other, just as God in Christ also has forgiven you."
Do your words show a tender heart? There is no call for us to be wrathful—God can manage that in the end. But kindness accomplishes so very, very much. Let's practice that ever hour.
"For the entire Law is fulfilled in in this one word: "You shall love your neighbor as yourself."—Gal 5:14
