He discovered that ten minutes of Laurel and Hardy would give him two hours of pain-free sleep. He kept up his treatment schedule until he laughed himself back to health. But there's just enough truth in it to pay close attention. Laughter really is healthy for us. I am aware there is a shadow side of human nature that hates laughter.
Some people think it is sinful to laugh, particularly in church.
I'm sure there are those who will think it's terrible that I would preach on the importance of laughter. But laughter is good for us. It is healthy. I'm convinced that our Lord understood the benefits of laughter. If you read the gospels with an ear for hearing it, you can pick up the ancient evidence of a laugh track that runs in the background.
