Even as Abraham "believed God, and it was counted to him for righteousness."

Know therefore that those who are of faith, the same are children of Abraham.

The Scripture, foreseeing that God would justify the Gentiles by faith, preached the Good News beforehand to Abraham, saying, "In you all the nations will be blessed."

So then, those who are of faith are blessed with the faithful Abraham.

that the blessing of Abraham might come on the Gentiles through Christ Jesus; that we might receive the promise of the Spirit through faith.

Now the promises were spoken to Abraham and to his seed. He doesn't say, "To seeds," as of many, but as of one, "To your seed," which is Christ.

For if the inheritance is of the law, it is no more of promise; but God has granted it to Abraham by promise.

If you are Christ's, then you are Abraham's seed and heirs according to promise.

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