22. The Scriptures say that Abraham had two sons. The mother of one son was a slave woman. The mother of the other son was a free woman.
23. Abraham’s son from the slave woman was born in the normal human way. But the son from the free woman was born because of the promise God made to Abraham.
24. This makes a picture for us. The two women are like the two agreements between God and men. One agreement is the law that God made on Mount Sinai. The people who are under this agreement are like slaves. The mother named Hagar is like that agreement.
25. She is like Mount Sinai in Arabia and is a picture of the earthly Jewish city of Jerusalem. This city is a slave, and all its people are slaves to the law.
26. But the heavenly Jerusalem which is above is like the free woman. She is our mother.
27. It is written in the Scriptures:“Be happy, Jerusalem.You are like a woman who never gave birth to children.Start singing and shout for joy.You never felt the pain of giving birth to children.But you will have more childrenthan the woman who has a husband.” Isaiah 54:1
28. My brothers, you are God’s children because of his promise, as Isaac was then.
29. The son who was born in the normal way treated the other son badly. It is the same today.
30. But what does the Scripture say? “Throw out the slave woman and her son! The son of the free woman will receive everything his father has. But the son of the slave woman will receive nothing.”
31. So, my brothers, we are not children of the slave woman. We are children of the free woman.
