Replacement of what? The Father is SPIRIT and thus are all His children born. Always has been and always will be. That is why all of the holy seedline genealogies are father-to-son; for the holy seed is produced by way of the preaching and the hearing of the Word of Truth. This is expounded in the Parable of the Sower and other similar idioms and proverbs. The preaching of righteousness began with the son of Seth, that is, Enosh, who is called the first herald or preacher of righteousness, (Gen 4:26), and that is why 2Pet 2:5 calls Noah the eighth herald or preacher of righteousness, (though not many English translations appear to understand what the text is truly saying). The holy seed is by the Spirit of the Word having been sown in the soil of the heart and bringing forth fruit, (producing offspring).
1) Enosh - first herald of righteousness, (Genesis 4:26 YLT)
2) Cainan - second herald of righteousness

So you deny spiritual Israel Jesus talks about?
