2 Corinthians 12:9-10

And he said vnto me, My grace is sufficient for thee: for my power is made perfect through weakenesse. Very gladly therefore will I reioyce rather in mine infirmities, that the power of Christ may dwell in me.

Therefore I take pleasure in infirmities, in reproches, in necessities, in persecutions, in anguish for Christes sake: for when I am weake, then am I strong.
