The same with Abraham. There was a man named Abraham who married a woman named Sarah. But the story of Abraham as written in the Bible is not about that ancient Abraham. It is taking the ancient Abraham and using him as a character to invoke an Abraham yet to come. It is about a FUTURE Abraham. Both Jesus and Paul say so ...

[Paul says] "But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise. Which things are an ALLEGORY: for these are the two covenants; the one from the mount Sinai, which gendereth to bondage, which is Agar."

Take careful note how Paul says the story of Abraham is ALLEGORY of the followers of Christ, the New Abraham that Paul is helping Christ to create at that very time.

Hagar is Israel after the Flesh, under bondage to the Law of Mount Sinai. Sarah is the mother of the New Jerusalem, the Israel of all nations born after the Spirit. Thus Abraham was divided into two seeds, one earthly, and one spiritual, and the one would be at odds with the other, as foretold to Eve and the Serpent. So it is the spiritual seed of Abraham that enters the kingdom to come, and the fleshly seed that must be put to death:

"Ye must be born again!"

"Ye must be born of water and of spirit ..."

What flowed from the side of Jesus onto the earth? Water and blood.

"The life (spirit) of flesh is in the blood."

It has been in front of our faces all these centuries, but most have not seen because they did not heed the warnings about interpreting the scripture with vain fables and false histories:

"Neither give heed to fables and endless genealogies, which minister questions, rather than godly edifying which is in faith: so do."

"But refuse profane and old wives' fables, and exercise thyself rather unto godliness."

"And they shall turn away their ears from the truth, and shall be turned unto fables."

"Not giving heed to Jewish fables, and commandments of men, that turn from the truth."

"For we have not followed cunningly devised fables, when we made known unto you the power and coming of our Lord Jesus Christ, but were eyewitnesses of his majesty."

"Making the word of God of none effect through your tradition, which ye have delivered: and many such like things do ye."

(I have been drafting a homile set on this subject.)
