"False witnesses did rise up; they laid to my charge things that I knew not." Psalms 35:11.

God desire His children to have a pledge in their heart that they would not speak any word against a sister or brother. Children of God who are born again by His spirit are to remember that they also are tempted. It may be stronger than you.The Adventist writter once wrote"Those who are really the most erring are in greatest need of your help. Do not gossip about them in the love of Jesus and the love of the truth and try to help them." In Heavenly places. page. 289.

The people you know about their errors, time to time their errors had been presented before you either through vision, dream etc or maybe you have seen them physically, the community are talking about them. These the most errors are the one in greatest need of your help. There is no need to gossip about their bad remarks and habits. Only the love of Christ which dwell within you can bring back the most erring to the Lord Jesus Christ.
