No matter how just your words may be, you ruin everything when you speak with anger. (John Chrysostom, 5th century Early Church Father)
You can’t take back your words once you’ve spoken them. It’s not like the delete key on your computer. What’s worse, you can’t remove the attitude those words relayed. The anger may be remembered even when the words are forgotten. Remember telling your kids to count to ten before . . .? It works for adults, too. Try it before you hurt someone with angry words.
In your anger do not sin: Do not let the sun go down while you are still angry (Ephesians 4:26).
