At the very least, we can all stand to realize that every single one of us has some thorn (or thorns) or another that can be an obstacle to our obedience to and faith in God.

I'm not sure it matters so much -what- Paul's thorn was as it does that he had one and we can all relate. So rather than dwell on the specifics of his struggle, what can we learn from the way he navigated it?
