I’ve heard this important saying said a slightly different way with the acronym THINK. Is what you’d like to say: Thoughtful, Honest, Intelligent, Necessary, and Kind?
At my former church, Grace Bible Fellowship of Silicon Valley, many church members and pastors/elders used vicious, vile hate speech and were terribly verbally abusive. Many former church members were shocked at how bad and abusive their speech was at GBFSV. It is not like Jesus and they did a great deal of damage.
