Jars of Clay

I've been thinking about this verse a lot lately. I doubt myself a lot, if I can actually do what God has called me to do. The truth is I shouldn't have any faith in my ability, but realize that I am weak and inadequate for the task....It's the opposite of what you would expect to hear, right?
The thing is, God often uses the weak, because it points people to put their trust in Him, not in a person. It's always about Him, it's not about us.
