We are all, myself included, infected with the vocabulary of entertainment, the vocabulary of amusement—infected. “Having fun.” “Having a blast.” This is where we are at home. We are at home with entertainment. This is our default vocabulary resource. This is our native air. The vocabulary of earnestness and gravity and depth and weightiness and substance, these are foreign. They make us feel awkward. They are not natural to us. And that is my lament. It is not about words. We have borrowed the language of entertainment to describe sacred, weighty, serious, holy joys. And the best thing we can say to being an ambassador of the King of kings is, “It is a blast.” I regard that as tragic—and not just a vocabulary tragedy, but a spirit tragedy, a life tragedy, a huge loss in the church and in life.
…If anyone thinks that I want ministers to become boring or somber or gloomy or melancholy, let me close like this: Unbroken seriousness of a melodramatic or somber kind will inevitably communicate a sickness of soul to the great mass of people, and rightly so…The real battle in life is to be as happy in God as we can be, and that takes a very special kind of earnestness…
So, my lament is not a lament about the word fun. It is a lament about the loss of the capacity to feel and express the fun of cotton candy and roller coasters at the fair with our kids and the tear-stained joy of soul-saving ministry in the service of a crucified, triumphant King. There is a difference, brothers. There is a difference. And it would be a good thing to use words that help people feel the difference.
