And the Scripture, anticipating God's justification of the Gentiles by faith, announced the gospel to Abraham beforehand in the words, In thee shall all the Gentiles be blessed.

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

Even as Abraham believed God and it was counted to him for righteousness?

Notice then that the true sons of Abraham are children of faith.

So then they who are children of faith are blessed with Abraham the faithful;

to the end that in Christ Jesus the blessing of Abraham might come upon the Gentiles, so that through faith we might receive the promised Spirit.

Now it was to Abraham that the promises were spoken, and to his offspring. God did not say, "offsprings" as if speaking of many, but "and to your offspring," as of one; and this is Christ.

For if the inheritance comes from law, it no longer comes from a promise; but God did give it as a free gift to Abraham by a promise.

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