Speak not evil one of another, brethren. He that speaketh evil of his brother, and judgeth his brother, speaketh evil of the law, and judgeth the law; but if thou judge the law, thou art not a doer of the law, but a judge.
Living in this world, where most people speak their opinions about other people, many Christians can become judgmental. We are not to be like everyone else. Our attitudes should be different. Jesus said to pray for people instead of pointing out their faults. Stop and ask God to help you be the person you should be, and let Him judge others.
