I want to suggest that commending oneself as a minister of God consists of living and acting and speaking in such a way that others think not of you but of him. They don't so much look to you as through you, and in the light of your life see him. Again, to use the words of the title above, it means conducting yourself in such a manner that when others see you, God looks good! Let me explain this by asking a series of pointed (and painful) questions.
At the end of his list of questions is this conclusion:
To use Paul's word, when I "minister" among you, are you captivated by my credentials or energized to find satisfaction in God's merciful sufficiency?
Paul couldn't have cared less about his own reputation, unless by seeing him they savored God. If his weakness magnified God's power, then by all means, watch. So long as his life was a window through which others might behold the goodness and grace of Christ, he was more than happy to commend himself to their scrutiny.
"Don't look at or to me," said Paul, "but through me, as a minister of God, to the fountain of all goodness and grace."
So again, when others see you, does God look good?
