Children Born Free or Slave (Hagar and Sarah)

Have you traced your family tree? How far back? Any dark characters or famous people?
The importance of the genealogy of Jesus, the Christ (Messiah-King)
Abraham, Isaac, and Jacob
Hagar & Ismael compared with Sarah & Isaac

1. Abraham had two sons
V22 “For it is written that Abraham had two sons, one by the slave woman and the other by the free woman. His son by the slave woman was born in the ordinary way; but his son by the free woman was a result of the promise.”
There are two lines: one from Ishmael and one from Isaac and later: one from Esau and one from Jacob; the remnant principle that also runs through the whole OT. As Paul wrote in Romans 9:6 “not all who are born of Israel are Israel”

2. Old Covenant – present Jerusalem; New Covenant – New Jerusalem
“These things may be taken figuratively, for the women represent two covenants.”
“One covenant is from Mount Sinai and bears children who are to be slaves: This is Hagar. Now Hagar stands for Mount Sinai in Arabia and corresponds to the present city of Jerusalem, because she is in slavery with her children.”
“But the Jerusalem above is free and she is our mother.”

3. Children of the free woman; not the slave woman
“Now you, brothers, like Isaac, are children of promise.”
“At that time the son born in the ordinary way persecuted the son born by the power of the Spirit. It is the same now. But what does the Scripture say? Get rid of the slave woman and her son, for the slave woman’s son will never share in the inheritance with the free woman’s son”
Then Paul concludes this section
V31 “Therefore, brothers, we are not the children of the slave woman, but of the free woman.”

Conclusion:
We are children or descendants by faith in Sarah’s line and not via Hagar’s
