Why We Should Stop Criticizing

I have been wasting many times thinking of mistakes people do. Well, I know it's not a good habit to preserve instead I know that this must be stopped, somehow I just can't stop. It has been a 'part' of me to concern about what people do (to me, or not). I live in a kind of dormitory which allows me to know many different types of people with different habits and lifestyles. Sometimes it's beyond my consciousness that my instinct actively learns people and issuing in judging them. I am sick of this and am striving to kick this off me. I have the same feeling every time I criticized someone: superior, excellence, clean. I know this is ugly, but this is one weakness that I-or anyone else-can't overcome.

Believe me, God helps anyway. He lets one incident happen to me that ruins all my stances. One day after a meeting, I was having an open-ended conversation with a sister. Like usual she asked me things that surely I can answer. It happened around three months ago if I'm not mistaken. It wasn't real clear in my mind what I was saying but I did mention something about what concerned me most at that time: having a part-time job. Receiving scholarship restricts me to have any job however I was somehow allowed to it (secretly). I was told months after that that incident was a total mistake. I should've NOT said anything about having any job. I feel like being guilty of something I am not sure about but now it's crystal clear. It was my fault. See, I make mistakes. Why not think that I do make mistakes right at the time I feel like criticizing someone? Why do I tolerate my own fault otherwise judging others for things they might not do? Now that I think I've learned my lesson, here comes the test. At the same day, actually night, we were driving to a meeting. A brother's driving. He's a newbie driver. Many times he failed to move the car after he stopped for a while during red lights. It freaked me out every time he repeated the same thing. Now that we're on our way, I wonder if he's learned his lesson. The car stopped at the red light. I keep asking. When the light turns green, the car moves. He learns. I shut my mouth. 

 One thing I learn-thank God-is that every time I think that someone's going to fail or someone never learns, all those kind of criticisms ALWAYS refer back to myself. I am the one who fail in so many things, and also I am the one who never learn. Lord have mercy on me! Help me to learn my lesson this time! 

For with what judgment you judge, you will be judged; and with the measure you use, it will be measured back to you. 

Matthew 7:2 NKJV
