If I didn't already like what I had read of Frederick Buechner's work, this quote that I heard in this morning's sermon made me like Buechner even more. Hopefully you enjoy it just as much:
"Whether your faith is that there is a God or that there is not a God, if you don't have any doubts you are either kidding yourself or asleep. Doubts are the ants in the pants of faith. They keep it awake and moving."
In peace and grace.
