for by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, that no one would boast. For we are his workmanship, created in Christ Jesus for good works, which God prepared before that we would walk in them.
Ephesians 2:6 and raised us up with him, and made us to sit with him in the heavenly places in Christ Jesus,
Ephesians 2:7 that in the ages to come he might show the exceeding riches of his grace in kindness toward us in Christ Jesus;
Ephesians 2:8 for by grace you have been saved through faith, and that not of yourselves; it is the gift of God,
Ephesians 2:9 not of works, that no one would boast.
Ephesians 2:10 For we are his workmanship, created in Christ Jesus for good works, which God prepared before that we would walk in them.
Ephesians 2:11 Therefore remember that once you, the Gentiles in the flesh, who are called “uncircumcision” by that which is called “circumcision”, (in the flesh, made by hands);
Ephesians 2:12 that you were at that time separate from Christ, alienated from the commonwealth of Israel, and strangers from the covenants of the promise, having no hope and without God in the world.
The verse centers on "for good", "saved", "created", "good works", "grace", "faith", "gift of God", and "his workmanship". It is saying that salvation is received as God's gift through faith, so boasting is pushed out by the wording itself.
The nearby context moves from verse 7's "that in the ages to come he..." into verse 11's "Therefore remember that once you the Gentiles...", so "for good" and "saved" belong inside that flow. In Saved by Grace for Good Works, the local focus is grace, faith, new creation, and good works.
A plain takeaway is to answer the verse's own emphasis on "for good" and "saved" with trust shaped by these words, not by a vague optimism outside the passage.
