James 3:14-16, 18

But if you are selfish and have bitter jealousy in your hearts, do not brag. Your bragging is a lie that hides the truth. That kind of “wisdom” does not come from God but from the world. It is not spiritual; it is from the devil. Where jealousy and selfishness are, there will be confusion and every kind of evil.

People who work for peace in a peaceful way plant a good crop of right-living.
