I have found that people tend to joke about things they are uncomfortable with, unsure of, or just don't know. What can you do when that happens? Shhh- be quiet and listen to how Holy Spirit guides. It may be that you are to be quiet. It may be that you are to speak. If you are to speak- speak truth. Do you know the Truth? Then get your guidance and if you are to speak, speak truth. Nothing more is needed. Yes, they may squirm, but it has nothing to do with you, so do not take it personally. Speak truth. Listen for truth. Bask in the presence of Truth. And then rest in Truth. enough for now.
