Abraham was born again, as was Abel, Job, Moses, and so on. All of the faithful in Romans 11 were born again because faith/faithfulness is a fruit of the Holy Spirit.
“However, you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. But if anyone does not have the Spirit of Christ, he does not belong to Him.” (Romans 8:9) (NASB95)
Being born again is being resurrected, No one except Christ has ever been born again. Born again isn't salvation. You must be saved before you can be resurrected (born again).
You must be born again to enter the Kingdom of God, John 3:3
Flesh and blood can't inherit the Kingdom of God, 1 Corinthians 15:50
The ONLY way both of those verses can be correct is when being born again means resurrection

Jesus Christ did NOT TELL US Gentiles to preach the Gospel. His earthly ministry was totally TO Israel, Matthew 15:24 . The Gospel He was talking about was the Kingdom (Earthly) Gospel, which was solely for Israel ( Acts of the Apostles 1:6 ). This same Gospel was preached during the all-Israel Acts period by both the 12 and Paul, since the ENTIRE purpose of Acts was to get Israel to repent, as a nation, so Christ would return and Israel's Kingdom would begin. Christ said He would't return until Israel accepted Him, Matthew 23:39 . The Gospel of the Grace of God, that Paul eventually preached, was that the Gentiles could partake of Israel's blessings without keeping the law. There are several Gospels in the Bible.
********************************************
There are only 2 churches in the Bible. One for Israel and one for the Gentiles
One is solely for Israel. It started under the name of The Church in the Wilderness ( Acts of the Apostles 7:38 ). The Church in the Gospels and the Church in Acts was the same Church. No new church started in the Gospels or Acts. In Acts, the Gentiles were grafted into that same Church.
The Gentiles have a totally different Church that has absolutely nothing to do with Israel. It's the present day Church which is the Body of Christ, where Christ is the Head, found only in Paul's 7 post-Acts books.. It is not the same "body of Christ" as in 1Cor for several reasons.
(1) One is that the Hope in all-Israel Acts was the New Jerusalem, whereas after Acts, the Hope is Above the starry Heavens, where Christ sits at God's right hand.
(2) Members of the "body" in 1Cor 12 are "eyes" and "ears", parts of the Head. This can't happen after Acts, where Christ is the Head.
(3) Also, the Acts church has the "Rapture" and the after-Acts church has the "Appearing".
(4) Also, everything Paul taught and wrote during Acts can be found in the OT, Acts of the Apostles 26:22 , but, after Acts, nothing Paul taught or wrote was in the OT, since it ALL had been hidden in God since the world began ( Ephesians 3:9 , Colossians 1:26 ), until revealed to Paul by Jesus Christ, Ephesians 3:3

The greatest travesty in the world today is the all-powerful, Judaising, Pagan, KNOW-NOTHING Denominational Church system that, through the wiles of Satan, teaches UNOBTAINABLE Jewish doctrine to know-LESS-than-nothing Gentiles. It's sole purpose is to keep you dumbed down and keep you out of the Highest Heaven, where Satan aspired to go but wasn't allowed to.
Through this abhorrent System, Satan has successfully prevented billions (literally) from going to Heaven. Every Church-goer in the world, who believes their Judaising preacher, will end up one the New Earth with a terrestrial body, with 2 dimensional freedom, that is kept alive by the pure water coming out of the New Jerusalem and the fruits from the tree of life.
Wouldn't you rather be in 4-dimensional GLORIOUS body in the Heaven of Heavens?
