Yes, but my point was about the other part of the verse - "
in you all the families of the earth shall be blessed.”
Yes, family means a circle of relatives. I do know what it means.
However the verse in question clearly says
all families on earth - this is not just a reference to Abraham's descendants.

I used the passage in the same way Paul did in his letter to the Romans.
Yes, everything in the OT points to Jesus. The whole Bible is a unified whole that points to Jesus. No argument here.
Luke was not a Jew.
Who was Luke in the Bible? Was Luke a doctor? Why did God choose Luke to write a Gospel and the Book of Acts?

Mormonism is heresy.
Yes, salvation is of the Jews, because Jesus was a Jew. Yes, the Jews wrote the OT, obviously. Yes, the NT church began with Jews in Jerusalem. But it didn't stop there. The church grew rapidly, and is still growing today. And consists of both Jews and Gentiles, and both are one in Christ.
Paul goes to great pains in his letters to point out the unity that we now have in Christ - there is no longer Jew or Gentil ... but both are one in Christ Jesus. We all make up the body of Christ. "
There is one body and one Spirit—just as you were called to the one hope that belongs to your call— one Lord, one faith, one baptism, one God and Father of all, who is over all and through all and in all." Ephesians 4:4-6. The body of Christ is not split in two - one a covenant family and the other a non-convenant family. It is united.
You can dismiss what I say if you like, but it is simply untrue to say that Bible was written by Jews and to Jews. As I pointed out Luke was not a Jew. Paul wrote to many churches that were a mix of Jews and Gentiles. Paul clearly addresses the Gentiles in his letter to the Ephesians (Eph 2:11). Titus was a Gentile (as indicated in Galatians 2:3).
