My grace is sufficient for you

"but he said to me, “My grace is sufficient for you, for power is made perfect in weakness.” I will rather boast most gladly of my weaknesses,* in order that the power of Christ may dwell with me."  (2 Corinthians 12: 9)

"The Lord has more need of our weakness than of our strength: our strength is often His rival; our weakness, His servant, drawing on His resources, and showing forth His glory. Man's extremity is God's opportunity; man's security is Satan's opportunity. God's way is not to take His children out of trial, but to give them strength to bear up against it "  (Commentary Critical and Explanatory on the Whole Bible"
