Can God use you?

That was the question we were asked at St George’s on Sunday night. Things for me recently haven’t been brilliant, and I had forgotten that God is in charge, not me. I am once again having to make some major decisions and have been trying to make them on my own. The sermon on Sunday really reminded me that I need to trust God, His plan for me and not rely on my own plan. That's what I intend to do from now on.
So can God use me? You bet He can, I’m just waiting to see how.
Am I the only Christian to struggle with this?
