In my weakness...

He is strong.  

2 Corinthians 12:9-11  (NIV)

⁹ But he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me. ¹⁰ That is why, for Christ’s sake, I delight in weaknesses, in insults, in hardships, in persecutions, in difficulties. For when I am weak, then I am strong.

Galatians 6:9 (NIV)

¹⁰ So do not fear, for I am with you; do not be dismayed, for I am your God.  I will strengthen you and help you; I will uphold you with my righteous right hand.
