No matter who you are, if you judge anyone, you have no excuse. When you judge another person, you condemn yourself, since you, the judge, do the same things.
Romans 2:1
Don’t judge others for their weaknesses. If the only thing you can control is yourself, then complaining about the sins or weaknesses of other people is a waste of your time. No matter how much you whine about them to how many people, you aren’t going to change them. All you’re doing is sinning by finding fault and complaining. When you are constantly occupied with things beyond your control, you just end up feeling frustrated and bitter—not the holiest of emotions.
The sins of other people will get more and more obvious the closer you draw to God, but so will your own sins, so concentrate on those and leave the sins of others to them. Stop the wrestling with thoughts of how bad they are and confess that by just thinking such a thing, you show yourself to be worse than them, according to Romans 2:1.
You should find some comfort in this thought: no matter who you are or what you’ve done, this verse applies to the people around you as well. Just like we are told in Romans 3:9–10, everyone is under the power of sin, and that means that none of us should think any more highly or worse of ourselves than is proper. We find the most hope in all of this in Romans 8:1, which says, “So those who are believers in Christ Jesus can no longer be condemned.” We are all down here in the same boat. And while we are to judge right from wrong (see 1 Cor. 2:15; 1 Thess. 5:21) and to avoid sin at all costs, we are not to spend our strength on judging others when there is plenty of sin within us that needs to be addressed.
