Isaiah 57:12 vs. Ephesians 2:8-9: Grace Works
Connect Isaiah 57:12 with Ephesians 2:8-9 on grace versus works.

Seeing God’s Verdict on Human Effort

Isaiah 57:12: “I will expose your righteousness and your works, and they will not profit you.”

• The Lord announces He will lay bare every “righteous” deed people rely on.

• “Expose” pictures pulling back the curtain—no work remains hidden.

• Result: those works “will not profit.” However sincere or impressive, they cannot earn favor or life with God (cf. Isaiah 64:6).


Grace on Display

Ephesians 2:8-9: “For it is by grace you have been saved through faith, and this is not from yourselves; it is the gift of God, not by works, so that no one can boast.”

• “By grace” points to God’s unearned kindness.

• “Through faith” shows our response—trusting, not achieving.

• “Not from yourselves… not by works” flatly rules out any contribution of human effort.

• “So that no one can boast” echoes Isaiah’s warning: works leave us empty-handed, grace leaves us praising God.


The Link: Works Exposed, Grace Offered

Isaiah 57:12 tears down self-reliance; Ephesians 2:8-9 builds up God-reliance.

• Both passages confront the same issue from opposite sides:

– Isaiah shows works failing.

– Ephesians shows grace succeeding.

• Together they paint one seamless gospel: when our deeds are uncovered and found wanting, Christ’s gift stands ready to save.


Why Works Fail and Grace Succeeds

• Works are tainted by sin (Romans 3:23).

• Law reveals sin but cannot remove it (Romans 3:20).

• Grace flows from God’s mercy, not merit (Titus 3:5).

• The cross fully satisfies justice, making room for unstoppable grace (2 Corinthians 5:21).


Living in the Light of Grace

• Trade self-promotion for humble gratitude—“Let the one who boasts, boast in the Lord” (1 Corinthians 1:31).

• Serve God eagerly, not to earn salvation but because salvation is already secured (Ephesians 2:10).

• When tempted to measure worth by performance, remember Isaiah 57:12; when tempted to despair over failure, remember Ephesians 2:8-9.

The exposure of our works drives us to the gift of grace; the gift of grace frees us to walk in works God now prepares for us.

How can Isaiah 57:12 guide us in examining our spiritual motivations?
