Do not speak evil against one another, brothers. The one who speaks against a brother or judges his brother, speaks evil against the law and judges the law. But if you judge the law, you are not a doer of the law but a judge.
-James 4:11 ESV
James sums up the past chapter and a half with this thought. Don't speak evil. It's so easy to speak evil. So easy to judge. Just don't do it. Have you ever tried that?
But how much harder is it to build someone up? To compliment someone? I dare you to build someone up this next week. Speak life into people, and don't destroy them with your words. Compliment, encourage, bear someone's burdens, don't hate, fight, and belittle. It's not your job. The world already does that, true christians don't need to.
