Galatians 4:21-31 - Hagar And Sarah Represent Two Covenants
21 Tell me, you who are bent on being under the Law, do you not listen to [what] the Law [really says]? 22 For it is written that Abraham had two sons, one by the slave woman [Hagar] and one by the free woman [Sarah].
Break forth into a [joyful] shout, you who are not in labor;
For the desolate woman has many more children
Than she who has a husband.”
28 And we, [believing] brothers and sisters, like Isaac, are children [not merely of physical descent, like Ishmael, but are children born] of promise [born miraculously]. 29 But as at that time the child [of ordinary birth] born according to the flesh persecuted the son who was born according to [the promise and working of] the Spirit, so it is now also.
For never shall the son of the bondwoman be heir and share the inheritance with the son of the free woman.”
31 So then, believers, we [who are born again—reborn from above—spiritually transformed, renewed, and set apart for His purpose] are not children of a slave woman [the natural], but of the free woman [the supernatural].
