Galatians 4:26-31

²⁶In contrast to that, there is an invisible Jerusalem, a free Jerusalem, and she is our mother--this is the way of Sarah.k

²⁷Remember what Isaiah wrote: Rejoice, barren woman who bears no children, shout and cry out, woman who has no birth pangs, Because the children of the barren woman now surpass the children of the chosen woman.l

²⁸Isn''t it clear, friends, that you, like Isaac, are children of promise?

²⁹In the days of Hagar and Sarah, the child who came from faithless connivance (Ishmael) harassed the child who came--empowered by the Spirit--from the faithful promise (Isaac). Isn''t it clear that the harassment you are now experiencing from the Jerusalem heretics follows that old pattern?

³⁰There is a Scripture that tells us what to do: "Expel the slave mother with her son, for the slave son will not inherit with the free son."m

³¹Isn''t that conclusive? We are not children of the slave woman, but of the free woman.
