Scripture's strength passages weren't written by strong people on good days. They were written by the surrounded, the grieving, and the running-on-empty — which is exactly why they hold. Strength, in these verses, is something you're given, not something you prove.
In the Bible, strength is supplied, not proven: "God is our refuge and strength, a very present help in trouble" (Psalm 46:1). It flows specifically to the empty — "he gives power to the faint, and increases strength to him who has no might" (Isaiah 40:29) — and it operates inside weakness rather than after it: "my power is made perfect in weakness... when I am weak, then am I strong" (2 Corinthians 12:9-10). Even joy is assigned as a strength source (Nehemiah 8:10). Scripture's strong people are the sustained, not the self-sufficient.
“God is our refuge and strength, a very present help in trouble. Therefore we won’t be afraid, though the earth changes, though the mountains are shaken into the heart of the seas; though its waters roar and are troubled, though the mountains tremble with their swelling. Selah.”
"God is our refuge and strength, a very present help in trouble." The psalm then imagines the worst: earth giving way, mountains falling into the sea — total structural collapse — and concludes "therefore we won't be afraid." The confidence isn't that the mountains won't move. It's that the refuge isn't built on them. "Very present" is the key phrase: help that is actually there, in the trouble, not observing from outside it.
“Then he said to them, “Go your way. Eat the fat, drink the sweet, and send portions to him for whom nothing is prepared, for today is holy to our Lord. Don’t be grieved, for the joy of Yahweh is your strength.””
"The joy of Yahweh is your strength." The context is specific: the returned exiles hear the law read aloud and start weeping over their failures — and Nehemiah stops them. Don't grieve, he says; eat, drink, share, because this day is holy. Joy here isn't a mood that happens to you. It's assigned, as a source of strength, to people who were busy feeling disqualified.
“He has said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Most gladly therefore I will rather glory in my weaknesses, that the power of Christ may rest on me. Therefore I take pleasure in weaknesses, in injuries, in necessities, in persecutions, in distresses, for Christ’s sake. For when I am weak, then am I strong.”
Paul begged three times for his affliction to be removed, and the answer was no — with a reason: "my grace is sufficient for you, for my power is made perfect in weakness." This is scripture's strangest strength verse: the weakness isn't the obstacle to God's power; it's the venue for it. "When I am weak, then am I strong" is not a paradox Paul solved. It's one he lived in.
A few more passages worth sitting with — each one honest about where it comes from.
“He gives power to the weak. He increases the strength of him who has no might.”
He gives power to the faint, and increases strength to him who has no might — strength for the specifically empty.
“I can do all things through Christ, who strengthens me.”
I can do all things through Christ — written from prison, about contentment in hardship, which makes it stronger, not weaker.
“Yahweh is my strength and my shield. My heart has trusted in him, and I am helped. Therefore my heart greatly rejoices. With my song I will thank him.”
Yahweh is my strength and my shield; my heart trusted in him, and I am helped — past tense: it worked.
“Yah is my strength and song. He has become my salvation. This is my God, and I will praise him; my father’s God, and I will exalt him.”
Yah is my strength and song — sung on the far shore of the Red Sea, by people who had just been cornered.
“Yahweh, the Lord, is my strength. He makes my feet like deer’s feet, and enables me to go in high places. For the music director, on my stringed instruments.”
Yahweh is my strength, and he makes my feet like deer's feet — sure-footedness on terrain that should be impossible.
“Finally, be strong in the Lord, and in the strength of his might.”
Be strong in the Lord, and in the strength of his might — the supply is named, and it isn't yours.
“In the day that I called, you answered me. You encouraged me with strength in my soul.”
In the day that I called, you answered me; you encouraged me with strength in my soul — strength delivered to the inside first.
