Now from those recognized as important (what they really were makes no difference to me; God does not show favoritism)—they added nothing to me.

So then, does God supply you with the Spirit and work miracles among you by the works of the law or by hearing with faith?

For all who rely on the works of the law are under a curse, because it is written: Everyone who does not continue doing everything written in the book of the law is cursed.

But the law is not based on faith; instead, the one who does these things will live by them.

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

And I say this: The law, which came 430 years later, does not revoke a covenant that was previously ratified by God and cancel the promise.

For it is written:

Rejoice, childless woman,
who does not give birth.
Burst into song and shout,
you who are not in labor,
for the children of the desolate are many,
more numerous than those
of the woman who has a husband.

But what does the Scripture say?

Drive out the slave and her son, for the son of the slave will never be a coheir with the son of the free woman.
