26 But our mother is the city of Jerusalem in heaven above, and she isn't a slave.
27 The Scriptures say about her,“You have never had children,but now you can be glad.You have never given birth,but now you can shout.Once you had no children,but now you will havemore children than a womanwho has been marriedfor a long time.”
28 My friends, you were born because of this promise, just as Isaac was.
29 But the child who was born in the natural way made trouble for the child who was born because of the Spirit. The same thing is happening today.
30 The Scriptures say, “Get rid of the slave woman and her son! He won't be given anything. The son of the free woman will receive everything.”
31 My friends, we are children of the free woman and not of the slave.
