As we are coming near to the end of this epistle, we see here a good summary of Paul’s idea of what constitutes the apostolic insignia. There are three elements that can be seen here. The first would be apostolic signs, works of power and authority. The second would be apostolic sacrifice, where Paul was willing to spend himself for the Corinthians. And the third element would be his apostolic fears—his concern for their spiritual well-being.
