[Paul’s] thrice-repeated prayer for the removal of the ailment was answered, not by his deliverance from it, but by his receiving the necessary grace to bear it – not simply to live with it but to be thankful for it. If his ministry was so effective despite this physical weakness, then the transcendent power was manifestly God’s, not his own. Infirmities like this were welcomed, together with the other hardships…if they were the condition on which the power of the risen Christ operated through him. They constantly reminded him not so much of his own inadequacy as of the total adequacy of Christ, in whom, when he was personally most weak, he knew himself to be most strong.
