I've always felt that one measure of good people is their ability to laugh at themselves! We all know folks, of course, who love to poke fun at others. But play a joke on them, or tell one at their expense, and they are easily offended. Why is that, if not that they are too insecure to face up to their own foibles?
I once heard my father refer to a hymn often sung by the earliest Covenanters that included a phrase something like "tell me my faults." Pietists recognize the wisdom in that, even while resisting the spirit of some who take it too far. What matters in the long run is one's ability both to tell a joke and receive one at his or her own expense. A good rule of thumb in that regard is probably learning the high art of telling jokes occasionally on oneself.
J.J. Daniels (1862-1957), a Covenant pioneer pastor, put it well, balancing his gifts as a story teller with the willingness to be a story receiver as well. His advice, written down by Herbert Palmquist, is full of communal wisdom and well worth pondering: "There is so much bad in the best of us, and so much more in the worst of us, that it behooves all of us to keep our eye on the rest of us."
