John Calvin on 2 Corinthians 12:5

5. Of such a man It is as though he had said “I have just ground for glorying, but I do not willingly avail myself of it. For it is more in accordance with my design, to glory in my infirmities If, however, those malicious persons harass me any farther, and constrain me to boast more than I am inclined to do, they shall feel that they have to do with a man, whom God has illustriously honored, and raised up on high, with a view to his exposing their follies.

2 Corinthians 12:6-10

6. For though I would desire to glory, I shall not be a fool; for I will say the truth: but now I forbear, lest any man should think of me above that which he seeth me to be, or that he heareth of me.

6. Nam si voluero gloriari, non ero insipiens: veritatem enim dicam: sed supersedeo: ne quis de me cogitet supra id quod videt esse me, aut quod audit ex me.

7. And lest I should be exalted above measure through the abundance of the revelations, there was given to me a thorn in the flesh, the messenger of Satan to buffet me, lest I should be exalted above measure.

7. Et en exellentia revelationum suppra modum efferrer, datus mihi fuit stimulus carni, nuntius Satanae qui me colaphis caederet, ne supra modum efferrer.

8. For this thing I besought the Lord thrice, that it might depart from me.

8. Supra hoc ter Dominum rogavi, ut discederet a me:

9. And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me.

9. Et dixit mihi: Sufficit tibi gratia mea: nam virtus mea in infirmitate perficitur: libentissime igitur gloriabor super infirmitatibus meis, ut inhabitet in me virtus Christi.

10. Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ’s sake: for when I am weak, then am I strong.

10. Quamobrem placeo nihi in infirmitatibus, in contumeliis, in necessitatibus, in persequutionibus, in anxietatibus pro Christo: quum enim infirmus sum, tinc robustus sum.
