A loose and undisciplined mouth.
Years ago, I was teaching a Wednesday evening class at our church. The class was about to begin. A woman was still talking as I attempted to start this class. I said something about her to the group, thinking it would be funny. Everyone laughed. Well, almost everyone. She did not laugh. In fact, the next day she called me and wanted to visit for a few minutes. My words had hurt her. They brought up memories of earlier humiliations in her life. Now, in front of everyone, her minister had embarrassed and humiliated her.
I felt awful. To get a quick laugh, I spoke without thinking. I really wished for a do-over.
Trust is everything in ministry. Ministers are people who have a great opportunity to help someone learn what it means to live as a Christ-follower. Yet, that trust is diminished when people witness that our speech is undisciplined. If we are not careful, we can speak in ways that are inappropriate, thoughtless, and even un-Christlike.
