25. Hagar, who stands for Mount Sinai in Arabia, is a figure of the present city of Jerusalem, in slavery with all its people.
26. But the heavenly Jerusalem is free, and she is our mother.
27. For the scripture says:“Be happy, you childless woman!Shout and cry with joy, you who never felt the pains of childbirth!For the woman who was deserted will have more childrenthan the woman whose husband never left her.”
28. Now, you, my brothers and sisters, are God's children as a result of his promise, just as Isaac was.
29. At that time the son who was born in the usual way persecuted the one who was born because of God's Spirit; and it is the same now.
30. But what does the scripture say? It says, “Send the slave woman and her son away; for the son of the slave woman will not have a part of the father's property along with the son of the free woman.”
31. So then, my brothers and sisters, we are not the children of a slave woman but of a free woman.
