2 Corinthians 12:9
GNT: But his answer was: “My grace is all you need, for my power is greatest when you are weak.” I am most happy, then, to be proud of my weaknesses, in order to feel the protection of Christ's power over me.
NKJV: And He said to me, “My grace is sufficient for you, for My strength is made perfect in weakness.” Therefore most gladly I will rather boast in my infirmities, that the power of Christ may rest upon me.
