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

then understand that the ones {who have faith}, these are sons of Abraham.

And the scripture, foreseeing that God would justify the Gentiles by faith, proclaimed the good news in advance to Abraham: "In you all the nations will be blessed."

So then, the ones [who have] faith are blessed together with Abraham who believed.

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

Now to Abraham and to his descendant the promises were spoken. It does not say, "and to descendants," as concerning many, but as concerning one, "and to your descendant," who is Christ.

For if the inheritance [is] from the law, [it is] no longer from the promise, but God graciously gave [it] to Abraham through the promise.

And if you [are] Christ's, then you are descendants of Abraham, heirs according to the promise.

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