Instead of saying it about them say it to them! Talking about someone has never improved a relationship! The Word says to be reconciled. It does not say slander and cause dissension.
If you don't like someone you don't need to form a committee to get others to dislike them also! The better thing to do is ask God why that person bothers you? God may be using that person to heal something in you by allowing them to rub you a certain way! The issue may not be them. It might be you! Talk to God before you talk to others. God can heal and bridge.
Remember, God wants His children to get along. Lead with love and you will never go wrong. Love covers sin, it doesn't broadcast it! Don't allow the enemy to use you to cast stones at your brother or sister!
Be Encouraged! ❤
