What does Isaiah 40:29 mean?
What is the meaning of Isaiah 40:29?

He gives power

• The subject is the LORD—the same sovereign Creator affirmed just a few verses earlier (Isaiah 40:26). His “power” is not abstract; it is the very force that formed and sustains the universe.

• Scripture consistently shows God as the source of all true power:

– “Great is our Lord and mighty in power; His understanding has no limit.” (Psalm 147:5)

– “Now to Him who is able to do immeasurably more than all we ask or imagine…” (Ephesians 3:20)

• Because God alone owns limitless power, He is fully able—and willing—to share it with His people.


to the faint

• “Faint” describes those whose strength is depleted, whether through trial, discouragement, or sheer exhaustion.

• The LORD’s invitation is personal:

– “Come to Me, all you who are weary and burdened, and I will give you rest.” (Matthew 11:28)

– “Let us not grow weary in well-doing, for in due time we will reap if we do not give up.” (Galatians 6:9)

• God does not shame the weary; He meets them right in their weakness.


and increases strength

• The promise goes beyond a one-time boost. “Increases” pictures an ongoing supply that grows as the need grows.

• This is the same principle Paul celebrated:

– “I can do all things through Christ who gives me strength.” (Philippians 4:13)

– “My grace is sufficient for you, for My power is perfected in weakness.” (2 Corinthians 12:9)

• The Father loves to multiply strength precisely where ours runs out.


of the weak

• “Weak” widens the scope: it covers physical frailty, spiritual struggle, emotional strain—any area where human resources fail.

• God chooses the unlikely and the unable so His glory is unmistakable:

– “God chose the weak things of the world to shame the strong.” (1 Corinthians 1:27)

– “If any of you lacks wisdom, he should ask God, who gives generously to all without finding fault.” (James 1:5)

• Our inability is never an obstacle to Him; it is the very context in which His strength shines brightest.


summary

Isaiah 40:29 assures us that the God who commands galaxies also stoops to empower His weary children. He personally supplies power, continually enlarges strength, and delights to do so for those who know they are weak. The verse calls us to exchange self-reliance for confident dependence on the One whose power never diminishes and whose generosity never ends.
