[RnMomof7]

Gal 3:8 And the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, [saying], In thee shall all nations be blessed.

.

Gen 12:3 And I will bless them that bless thee, and curse him that curseth thee: and in thee shall all families of the earth be blessed.

Gen 22:18 And in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice.

Gen 26:4 And I will make thy seed to multiply as the stars of heaven, and will give unto thy seed all these countries; and in thy seed shall all the nations of the earth be blessed;

[one Lord one faith one baptism]

I asked for Galatians 3:28 , not 3:8.

but actually i like your 3:8. The OT Jews thought Genesis was teaching all nations will be blessed by physical decendents of Abraham

Paul in Galatians makes clear that Genesis is talking about those that believe in Jesus Christ are the heirs to the promises to Abraham and all the nations of the world shall be blessed by the Church, as it brings the Gospel.
