These are good things.  Not to worry.  Doubt and uncertainty, and their cousin humility, are woven into the fabric of our Unitarian Universalist way of doing religion.  The sermon I gave to the UUSA search committee on my pre-candidating weekend was called “Living with Uncertainty.”  They had me deliver it to you, as well, a few months later.  It’s a topic we have touched on many times over the years, but worth seriously revisiting.
