7 To keep me from becoming conceited because of these surpassingly great revelations, there was given me a thorn in my flesh, a messenger of Satan, to torment me. 8 Three times I pleaded with the Lord to take it away from me. 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.
32 And what more shall I say? I do not have time to tell about Gideon, Barak, Samson, Jephthah, David, Samuel and the prophets, 33 who through faith conquered kingdoms, administered justice, and gained what was promised; who shut the mouths of lions, 34 quenched the fury of the flames, and escaped the edge of the sword; whose weakness was turned to strength; and who became powerful in battle and routed foreign armies. 35 Women received back their dead, raised to life again. Others were tortured and refused to be released, so that they might gain a better resurrection. 36 Some faced jeers and flogging, while still others were chained and put in prison. 37 They were stoned; they were sawed in two; they were put to death by the sword. They went about in sheepskins and goatskins, destitute, persecuted and mistreated-- 38 the world was not worthy of them.
28 Do you not know? Have you not heard? The LORD is the everlasting God, the Creator of the ends of the earth. He will not grow tired or weary, and his understanding no one can fathom. 29 He gives strength to the weary and increases the power of the weak. 30 Even youths grow tired and weary, and young men stumble and fall; 31 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.
13 I can do everything through him who gives me strength.
“I hear the Savior say, ‘Thy strength indeed is small; child of weakness watch and pray, find in Me thine all in all.’” Elvina M. Hall
“Jesus is the One who shows us the paradoxical route to meaning in a chaotic and hostile world. It’s the paradox of the gospel: Strength is found in weakness. Control is found in dependency. Power is found in surrender....God uses the frustrations of this life and the hurt of relationships to compel us to look beyond what we can control to the God who controls all things in order to woo us to himself. As we move from control to surrender, we move from chasing the wind under the sun to embracing God above it.” Dan Allender, Breaking the Idols of You
“The foundational principle of grace is that God’s kingdom priorities are completely inverted from those of the world. God’s plan is to magnify His saving mercy and grace not through human strength but rather through its weakness...The gospel of grace would remind us that we can’t be used until we operate not out of our own strength but in weakness, as we depend on Christ’s Spirit to show the reality of the cross.” Paul Kooistra
“When God is our strength, it is strength indeed; when our strength is our own, it is only weakness.” St. Augustine
“A primary qualification for serving God with any amount of success, and for doing God’s work well and triumphantly, is a sense of our own weakness. When God’s warrior marches forth to battle, strong in his own might, when he boasts, ‘I know that I shall conquer, my own right arm and my conquering sword shall get unto me the victory’, defeat is not far distant. God will not go forth with that man who marches in his own strength. He who reckoneth on victory thus has reckoned wrongly, for ‘it is not by might, nor by power, but by my Spirit, saith the Lord of hosts’. They who go forth to fight, boasting of their prowess, shall return with their gay banners trailed in the dust, and their armour stained with disgrace. Those who serve God must serve Him in His own way, and in His strength, or He will never accept their service. That which man doth, unaided by divine strength, God can never own. The mere fruits of the earth He casteth away; He will only reap that corn, the seed of which was sown from heaven, watered by grace, and ripened by the sun of divine love. God will empty out all that thou hast before He will put His own into thee; He will first clean out the granaries before He will fill them with the finest of the wheat......Your emptiness is but the preparation for your being filled, and your casting down is but the making ready for your lifting up.” C. H. Spurgeon
