Romans

And if ye be Christ’s, then are ye Abraham’s seed, and heirs according to the promise.

And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith:

Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.

That in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the sea shore; and thy seed shall possess the gate of his enemies;

And in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice.
