Words can hurt!
Right now, think of something someone said to you that still hurts. Perhaps a parent who sighs, “Why did I ever have another kid?” Or a teacher who declares, “You’re just too stupid to teach!” Or a spouse who yells, “I don’t love you anymore!” Sometimes the wounds caused by such words are never completely healed. Apologies help, but the effects cannot always be completely undone.
It takes real emotional and spiritual maturity to pause before speaking, and to consistently use our words for good and not for ill. (See James 1:26, 3:5)
Husbands and wives have a unique power to build each other up or tear each other down. Much of that power resides in your words. Speaking harshly to your spouse is one of the most destructive things you can do to your marriage.
