As Abraham believed God, and it was counted unto him for righteousness.

Then know that those who are of faith, the same are the sons of Abraham.

But the scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel to Abraham beforehand, That in thee shall all the Gentiles be blessed.

Therefore those who are of faith are blessed with faithful Abraham.

in order that the blessing of Abraham in Christ Jesus may come to the Gentiles; in order that we may receive the promise of the Spirit through faith.

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

For if the inheritance were by law, it is no more by promise: but God gave it to Abraham through the promise.

But if you belong to Christ then you are the seed of Abraham, heirs according to the promise.
