Well, there are right ways to correct other believers, and there are wrong ways to correct

other believers, so what's the difference?

Romans 14, 13 says this,

"...therefore, let us not pass judgment on one another any longer, but rather decide

never to put a stumbling block or hindrance in the way of a brother."

Here's John Piper explaining the meaning of this point from a 2005 sermon.

I take judgment who are you to pass judgment on your brother?

To mean two things. One, don't be critical of your fellow believer

without manifesting strong affections of brotherly love.

You can see how I'm saying it, because I'm leaving room for all the texts that say

correct one another, admonished one another, rebuked one another.

You've got to pass judgment if you're going to obey the Bible,

but this text got to mean something when he says, don't judge,

and the first thing, I'm picking it out from the word brother,

see the highlight on the brother, who are you to judge your brother?

In other words, be careful here that when you undertake to do some correcting,

some admonishing, some rebuking, let brotherhood be all over it,

not a spirit of condemnation. We created a word for this bad thing,

judge men tall. Where did that word come from?

Why was that created in English? This verse, that's why,

or something like this verse, everybody knows there's a right time to correct someone and tell

them they're doing something little stupid, and there's a way to do it in a wrong time to do it,
