This popped up in my reader from nakedpastor.com a while ago.
It made the rounds almost instantaneously in certain blog circles.
A couple of thoughts:
#1--I frequently feel this way. I'm in a place where it's easy for me to know what I don't think is true, but it is extremely hard for me to articulate what I do think is true. Negation is much easier than propagation. Whenever I want to put something forward about what/who God really is, I feel the limitations of my own words and thoughts. They're just not big enough. And even if they were, they are still bound by their own restraints.
#2--Even though nakedpastor hits it on the head with this one....as of yet I don't think that he, or anyone else who has posted it, has actually "shut up". So maybe we are good at ignoring the urge to simply be silent.
