So then, does He who provides you with the Spirit and works miracles among you, do it by the works of the Law, or by hearing with faith?

For as many as are of the works of the Law are under a curse; for it is written, “Cursed is everyone who does not abide by all things written in the book of the law, to perform them.”

Now the promises were spoken to Abraham and to his seed. He does not say, “And to seeds,” as referring to many, but rather to one, “And to your seed,” that is, Christ.

What I am saying is this: the Law, which came four hundred and thirty years later, does not invalidate a covenant previously ratified by God, so as to nullify the promise.

Now I say, as long as the heir is a child, he does not differ at all from a slave although he is owner of everything,

For it is written,
“Rejoice, barren woman who does not bear;
Break forth and shout, you who are not in labor;
For more numerous are the children of the desolate
Than of the one who has a husband.”

But what does the Scripture say?
“Cast out the bondwoman and her son,
For the son of the bondwoman shall not be an heir with the son of the free woman.”
