Just as Abraham believed God, and it was credited to him for righteousness,

then understand that those who have faith are Abraham’s sons.

Now the Scripture saw in advance that God would justify the Gentiles by faith and told the good news ahead of time to Abraham, saying, All the nations will be blessed through you.

So those who have faith are blessed with Abraham, who had faith.

The purpose was that the blessing of Abraham would come to the Gentiles by Christ Jesus, so that we could receive the promised Spirit through faith.

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.

For if the inheritance is from the law, it is no longer from the promise; but God granted it to Abraham through the promise.

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

For it is written that Abraham had two sons, one by a slave and the other by a free woman.
