What is a backbiter? Why should you not backbite? But what if the person you spoke evil of will never find out?
Read Ecclesiastes 10:20.
We are told to not even think bad thoughts toward someone. Because when we talk we say a whole lot more than words. An attitude comes through.
Do you know your friends likely learn more from talking with you than you think they do? Is that scary? It should actually be comforting.
There are little birds all around us. Our thoughts affect our words, so we need to cultivate loving attitudes toward all.
