Even as Abraham believed God, and it was reckoned to him as righteousness.

Know then that they that are on the principle of faith, these are Abraham's sons;

and the scripture, foreseeing that God would justify the nations on the principle of faith, announced beforehand the glad tidings to Abraham: In thee all the nations shall be blessed.

So that they who are on the principle of faith are blessed with believing Abraham.

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

But to Abraham were the promises addressed, and to his seed: he does not say, And to seeds, as of many; but as of one, And to thy seed; which is Christ.

For if the inheritance be on the principle of law, it is no longer on the principle of promise; but God gave it in grace to Abraham by promise.

but if ye are of Christ, then ye are Abraham's seed, heirs according to promise.

For it is written that Abraham had two sons; one of the maid servant, and one of the free woman.
