It started as a simple comment. Sarah posted a photo celebrating her new job, and her old coworker, Lisa, left a snarky remark: “Guess brown-nosing finally paid off.” Within minutes, others jumped in—some defending Sarah, others piling on with sarcasm and memes. By the end of the day, a happy moment had turned sour. Sarah deleted her post and blocked Lisa, while Lisa—still fuming—spent hours scrolling and stewing. What began as an “idle comment” fractured a friendship, spread negativity, and left both women wounded.

If you’re like me, you may be growing weary of the word sparring that dominates social media. People post outright lies with no concern for the consequences and throw insults like middle schoolers. It’s juvenile behavior that’s spiraling out of control—and it’s easy to get caught up in it. But we need to resist participating in such rhetoric.

Two chapters in Scripture give us sobering reminders about the power of words. In Matthew 12:36–37, Jesus says,

“But I say to you that for every idle word men may speak, they will give account of it in the day of judgment. For by your words, you will be justified, and by your words you will be condemned.”

Yikes… every idle word. That should give us all pause. I’m repenting as I write this.

James 3 also exhorts us to tame the tongue, reminding us that it is a small part of the body capable of both blessing and cursing. And Proverbs 21:23 tells us plainly:

“Whoever keeps his mouth and his tongue keeps himself out of trouble.”

These verses aren’t just moral reminders—they’re backed by relationship science. Research in psychology shows that harsh or idle words have measurable, negative consequences:

1. They damage trust and emotional safety. Studies by Dr. John Gottman at the University of Washington show that contempt, criticism, and sarcasm are among the most destructive behaviors in relationships. Once spoken, these words corrode intimacy and reduce the likelihood of repair.
2. They fuel negativity and suspicion. Social psychologists note that gossip and verbal aggression heighten anxiety and decrease empathy. The more negative talk you engage in, the more your brain wires itself toward suspicion and defensiveness—making genuine connection harder.
3. They create emotional contagion. Research on social media communication reveals that negative language spreads faster and more widely than positive posts. This emotional “contagion” means that our idle words don’t just harm one person—they ripple through communities.
4. They are habit-forming. Engaging in gossip or argument releases small bursts of dopamine—momentary pleasure that makes you crave more. As Paul warned in 2 Timothy 2:16,

“Besides that, they learn to be idlers, going about from house to house, and not only idlers, but also gossips and busybodies, saying what they should not.”

Idle words feed themselves. The more we speak them, the more natural they feel—and the more harm they cause.

The good news is that the same mouth capable of destruction can also bring life. Proverbs 18:21 reminds us, “Death and life are in the power of the tongue.” We can choose words that bless, encourage, and build up rather than tear down.

So before you post, comment, or repeat that juicy bit of gossip, pause. Ask yourself:

• Will this build up or tear down?
• Would I say this if the person were standing in front of me?
• Would I want to give account for these words before God?

Our relationships—and our spiritual health—depend on the words we speak. Let’s be people who use them wisely.
