Paul's Foolish Discourse

In this passage, Paul "dares" to enter into a boast -- but it is a boast with a purpose, and he is careful to warn his readers that boasting like he is about to do is foolishness. He makes it clear that there are boastings we should all make, but they are boasting about the great things God has done, in spite of our weaknesses, not our worldly "strengths". Why live and suffer the way Paul has? What does God call you to suffer for Him?
