James 4:11 (NLT)
11 Don’t speak evil against each other, dear brothers and sisters. If you criticize and judge each other, then you are criticizing and judging God’s law. But your job is to obey the law, not to judge whether it applies to you.

James, the half brother of Christ, warns against speaking evil of others. Katalaleite is the Greek word used in this passage for speaking evil; it signifies speaking anything which may hurt or injure another. One should not to speak out of ignorance or falsehood; nor should one seek to defile or defame another for their own pleasure. We are not to raise the persecution of the world against another, but instead we are to turn them from sin with the love of God. But first one must examine themselves and be not quick to look at the faults of others without looking at their own faults. We should obey God understanding we are not the ones to make judgments as to whether God’s justice applies to us.

Maybe you remember the Super Bowl commercial for Ameriquest Mortgage Company. A man walks into a convenience store talking on his cell phone. The man is wearing an earpiece so others are not easily aware of his conversation. He tells the person on the phone they are paying way too much for a deck. As he approaches the clerk at the counter he says on the phone, “you are getting robbed, you hear me, you are getting robbed” as he reaches for his wallet to pay for his drink. The clerk hearing his words and observing him reaching into his coat pocket turns and sprays the man with pepper spray, beats him with a bat, while his wife stuns him with a cattle prod. On the screen flashes the words, “Don’t judge too quickly”. Sometimes we think we have all the facts, but we jump to quick to a conclusion. We create our own judgment of a situation instead of letting God lead us. There is no harm in pointing out when someone is falling away from God as long as we understand the complete picture and we are lead by God to speak up and point out the obvious fault. We do it in love, not attempting to hurt someone, but to move them away from sin and back towards God.
