Bible Verses About Strength: 20+ Scriptures for Courage and Power

There are moments in life when our own reserves run dry — when grief, fear, illness, or exhaustion leave us with nothing left to give. It is precisely in those moments that Bible verses about strength become lifelines. Scripture does not promise us a life free from weakness; it promises us a God who meets us in our weakness and becomes our strength.

From the bold declarations of the Psalms to Paul’s words written from a prison cell, the Bible is full of passages that have sustained believers through impossible seasons. This guide gathers the most powerful scriptures on strength — organized by theme — so you can find the right word for your exact need today.

What Does the Bible Say About Strength?

The Bible consistently teaches that authentic strength is not self-generated. It comes from God. In 2 Corinthians 12:9-10, Paul writes that God told him: “My grace is sufficient for you, for my power is made perfect in weakness.” Paul’s response was astonishing: “I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me.”

This is the paradox at the heart of biblical strength. The moment we stop pretending to be strong enough on our own and turn to God, we access a power that is entirely beyond our natural capacity.

The Most Powerful Bible Verses About Strength

Philippians 4:13 — I Can Do All Things

“I can do all this through him who gives me strength.”

Philippians 4:13 (NIV)

One of the most quoted scriptures in all of Christianity, Philippians 4:13 is often taken out of context. Paul wrote it not as a promise of success in any endeavor, but in the context of learning contentment whether in plenty or in poverty (Philippians 4:11-12). The “all things” is specifically about enduring every condition of life through the strength Christ provides. That makes the promise even more profound.

Isaiah 40:29-31 — He Gives Strength to the Weary

“He gives strength to the weary and increases the power of the weak. 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)

Isaiah 40 ends one of the most majestic passages in all of Scripture with this promise. After forty verses describing God’s incomparable greatness — the one who weighed the mountains and called the stars by name — Isaiah draws the conclusion: this God renews the strength of the weary. When our legs give out, his power carries us.

Psalm 46:1 — God Is Our Refuge and Strength

“God is our refuge and strength, an ever-present help in trouble.”

Psalm 46:1 (NIV)

This psalm inspired Martin Luther’s famous hymn, “A Mighty Fortress Is Our God.” It was written for a people facing overwhelming enemies, and it anchors every source of strength in God alone. He is not a help who shows up occasionally — he is ever-present in trouble.

Joshua 1:9 — Be Strong and Courageous

“Have I not commanded you? Be strong and courageous. Do not be afraid; do not be discouraged, for the LORD your God will be with you wherever you go.”

Joshua 1:9 (NIV)

God spoke these words to Joshua as he prepared to lead the Israelites into the Promised Land after Moses’ death — one of the most daunting moments in the nation’s history. The command to be strong and courageous is not based on Joshua’s abilities. It is grounded entirely in God’s presence. That presence is still the foundation of our courage today.
