And he said to me: My grace is sufficient for thee; for power is made perfect in infirmity. Gladly therefore will I glory in my infirmities, that the power of Christ may dwell in me. For which cause I please myself in my infirmities, in reproaches, in necessities, in persecutions, in distresses, for Christ. For when I am weak, then am I powerful.
2 Corinthians 12:9-10
I'm reminded of another quote, 'He must increase, I must decrease.'
