2 Coríntios 12

7 and because of the surpassing nature of the revelations. For this reason, that I should not be puffed up, there was given to me a thorn in the flesh, an angel of Satan, to torment me, so that I should not be puffed up.

8 Regarding this I three times begged the Lord that it might leave me.

9 But he has said to me, "My grace is sufficient for you; for power is made perfect in weakness." Most gladly then will I boast in my weaknesses, that the power of Christ may abide upon me.
