But you, brothers and sisters, are children of the promise like Isaac.

For if the inheritance is based on the law, it is no longer based on the promise, but God graciously gave it to Abraham through the promise.

And if you belong to Christ, then you are Abraham’s descendants, heirs according to the promise.

But one, the son by the slave woman, was born by natural descent, while the other, the son by the free woman, was born through the promise.

in order that in Christ Jesus the blessing of Abraham would come to the Gentiles, so that we could receive the promise of the Spirit by faith.

But the scripture imprisoned everything and everyone under sin so that the promise could be given – because of the faithfulness of Jesus Christ – to those who believe.

Now the promises were spoken to Abraham and to his descendant. Scripture does not say, “and to the descendants,” referring to many, but “and to your descendant,” referring to one, who is Christ.

What I am saying is this: The law that came four hundred thirty years later does not cancel a covenant previously ratified by God, so as to invalidate the promise.

Is the law therefore opposed to the promises of God? Absolutely not! For if a law had been given that was able to give life, then righteousness would certainly have come by the law.
