Humor isn't the opposite of seriousness. Humor is the opposite of despair. Here are some thoughts about humor in the Bible.
The history of Israel begins—if it does not sound too impious—with a joke, a divine joke. The laughter of Abraham and Sarah at this joke was not so much a laughter of unbelief as of disbelief, as when we say “You can’t be serious” or “You’ve got to be kidding.” Yet it was a laughter that became the laughter of faith. Abraham and Sarah would be less inclined in the future to declare the impossible. And their laughter, in turn, would become the laughter of faith and hope for generations to follow.
God gave laughter to Sarah. Sarah declared, “God has brought me laughter! All who hear about this will laugh with me” (Gen. 21:5, NLT). Sarah had stopped dreaming that she and Abraham would have a baby, but the Lord was gracious to Sarah and did for Sarah “exactly what he had promised” (Gen. 21:1). God later told Moses that “I am the God of your father—the God of Abraham, the God of Isaac, and the God of Jacob” (Exod. 3:6). The Hebrew reader understands that Laughter (Isaac) is the father of Israel (Jacob).
Looking forward to sharing this Sunday with you.
