From the outset of this chapter Paul makes it clear what he is about to say is not the most Godly thing he has said. He then goes on a rant that would make any narcissist even more proud. Paul lays out his earthly credentials and his struggles for the sake of Jesus. Several times reminding that he is out of his mind for speaking like he is. Apparently Paul had enough of some folks undercutting his ministry with the Corinthian church. Since he was most likely in a Rome prison at the time of writing, he verbally corrects them. Paul is pissed off and he decides to let the people know it.
This is one of the great debates for any pastor. There are times when we simply get pissed off by what or who is pulling the attention of our congregations. I have a simple theory that says do not beat the sheep or they will bite back. Still there are times when I want to go into a sermon with both guns blazing and do a little boasting as Paul would say, about the sacrifice made to be a pastor in God's church. Still I do not, as it is not what God would have me do. At that point it is not longer sacrifice, it is whining.
So what are we to do? Let Paul speak and point people to Paul's words. We need to all ask who and what is demanding our attention? To who or what are we giving our attention? For as many people we are unhappy with, there are more than likely that many or more unhappy with us. While Paul's boast is part of the Scriptural record, I say humility is a better course. Even Paul knows his speaking is out of line.
