“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. 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.” (2 Cor. 12:9-10 NIV)
Weak things of the world
God has chosen the weak things of the world to put to shame the things which are mighty. (1 Cor. 1:27b NKJV)
He gives strength to the weary
“Even youths grow tired and weary, and young men stumble and fall; but those who hope in the LORD will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint. (Isaiah 40:29-31 NIV)
