Check out this brief post from the Gospel Coalition page, Paul's Downward Trajectory. I think it is fascinating. The way we think of Paul typically (this powerful preacher, fearless apologist, deep thinking theologian) is not how Paul describes himself. Paul saw himself over and over as unequal to the task, a weak man who found that the weaker he was, the more God was glorified. We could use more of that attitude in the church. There is no place for celebrities and fanboys of those celebrities in the church, only for weak bondservants who make much of Christ.
