Well, I'm just a regular joe too, so I put the whole thing in a very simple context that even I can understand, and it really boils down to this:
There are simply too many unexplained events that have occurred in my life that have turned out for the betterment of others close to me -- not just me, though that part is also true.
These events have occurred often despite my wishes and, in fact, I fought long and hard against some of them before I realized that despite my herculean efforts, there is a force that transcends anything I can even possibly imagine.
That force is God.
I find that the less I struggle, the better off I am. The more accepting I am (still very much a struggle, btw), the more peaceful I become. The more tolerant I am (whoa, now THERE'S a REAL struggle), the happier I am.
But all of that creates turmoil and uncertainty, despite my reasoning. I liken that to the fallibility of the human experience, and I am comforted in that is a universal condition that afflicts all of us.
I agree with Mrs. Smith -- if there are clergy who have "lost" their faith, I just don't see how they had it to begin with.
