There is a subtle irony in the nature of jokes. If you understand the joke, then you laugh. If you don't, and someone explains it to you, then the joke is much less funny. Jokes shine from understanding and loose their luster with explanation.
The same can be said about the life of faith.
The life of faith is one that seeks understanding a deep wisdom that is not only difficult to explain but sounds ridiculous. For instance, Jesus says the meek with inherit the earth and that the peacemakers are blessed; turn the other cheek, forgive our enemy seventy-seven times, the last will be first and the first will be last, and that Jesus is found among "the least of these." Frankly it all does not make any sense.
In my short time as a preacher, I can tell you it is getting to the point of silly to try to explain the wisdom of God. The wisdom of God is like a joke: not only does it often sound silly but it also shines in understanding and looses something with explanation.
This is why the mystics were less interested in prose and more interested in poetry. Why the ancients were less worried about doctrine and more interested in practicing the disciplines. The Church seems to be at her best when she is not explaining God (and getting bogged down in the silly conversations like the big bang vs. "creationism"), but seeking the peace that passes... well you know what I mean.
