“And since they did not see fit to acknowledge God, God gave them up to a debased mind to do what ought not to be done. They were filled with all manner of unrighteousness, evil, covetousness, malice. They are full of envy, murder, strife, deceit, maliciousness. They are gossips, slanderers, haters of God, insolent, haughty, boastful, inventors of evil, disobedient to parents, foolish, faithless, heartless, ruthless. Though they know God's righteous decree that those who practice such things deserve to die, they not only do them but give approval to those who practice them.”
God hates gossip!
Look at the list of sins he puts gossip into. It is there alongside “haters of God” and “inventors of evil” and “malice”. Gossip is immensely destructive. When you talk about someone to someone else, in a negative way—even if what you are saying is true—you are sinning against God, and you are hurting the person you are talking about, and you are hurting yourself.
Gossiping about others damages your own credibility. It also damages the relationship between them and the person you are talking to, and it hurts the person you are talking about. Gossip may make you feel better about something that irritates you about someone, but in the long run gossip hurts everyone.
God wants you to know that he is offended when you gossip about someone.
