Just as Abraham had faith in God and it was credited to him as uprightness.

So you see, the real descendants of Abraham are the men of faith.

The Scripture foresaw that God would accept the heathen as upright in consequence of their faith, and preached the good news in advance to Abraham in the words, "All the heathen will be blessed through you."

So the men of faith share the blessing of Abraham and his faith.

in order that the blessing given to Abraham might through Jesus Christ reach the heathen, so that through faith we might receive the promised Spirit.

Now the promises were made to Abraham and his line. It does not say, "and to your lines," in the plural, but in the singular, "and to your line," that is, Christ.

If our inheritance rests on the Law, it has nothing to do with the promise. Yet it was as a promise that God bestowed it upon Abraham.

And if you belong to Christ, then you are true descendants of Abraham and his heirs under the promise.

For the Scripture says that Abraham had two sons, one by the slave-girl, and one by the free woman.
