For by grace you have been saved through faith...

Only in the grace of God do I breathe.

God’s great love for His creation, mankind, brought forth the light of this world in human flesh…Jesus Christ. In Him and through we live now and for eternity. 

Praise Him who died in our place so that we could live!

The Greek word used here for faith , pistis, can refer to belief, trust, faith, or loyalty (faithfulness). People cannot accomplish salvation through their own effort. Faithlife Bible.

Salvation never originates in the efforts of people; it always arises out of the lovingkindness of God. We cannot do anything to earn our salvation. Some suggest that the gift of God modifies the word faith in this verse. Thus Paul is saying that even our belief in God does not originate in ourselves. This too is a gift. Because the sign of the Abrahamic covenant was circumcision, the Jews proudly referred to themselves as the Circumcision. Somewhat less kindly, they called Gentiles the Uncircumcision. NKJ Bible.

Ephesians 2:8–10 (NKJV)

⁸ For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, ⁹ not of works, lest anyone should boast. ¹⁰ For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.

Romans 4:16 (NKJV)

¹⁶ Therefore it is of faith that it might be according to grace, so that the promise might be sure to all the seed, not only to those who are of the law, but also to those who are of the faith of Abraham, who is the father of us all

Isaiah 19:25 (NKJV)

²⁵ whom the Lord of hosts shall bless, saying, “Blessed is Egypt My people, and Assyria the work of My hands, and Israel My inheritance.”

Romans 3:27 (NKJV)

²⁷ Where is boasting then? It is excluded. By what law? Of works? No, but by the law of faith.
