I appreciate your attempt to learn and your tone.
That is incorrect. Gentiles have always been allowed to join with Israel, just like I said before.
Exod 12:48-49 (AKJV/PCE)
(12:48) And when a stranger shall sojourn with thee, and will keep the passover to the LORD, let all his males be circumcised, and then let him come near and keep it; and he shall be as one that is born in the land: for no uncircumcised person shall eat thereof. (12:49) One law shall be to him that is homeborn, and unto the stranger that sojourneth among you.
This was always true and it's not new.
That is not new either, it is just that God method for doing so is now revealed.
I understand your confusion. Churchianity has been pounding these ideas into peoples heads for a long time.
Near to what? Near to God, not Israel.
Fellow citizens of what? God's household, not Israel.
Israel is currently cast away..... why would you want to be grafted into that?
The body of Christ is different; we have our conversation in heaven. Israel was told to pray for a kingdom on the earth.
The olive tree analogy is not about salvation from sin, it is about service to God. The body of Christ receive God's grace freely without the need for the nation of Israel and their covenants.
God has temporarily cast them away (set them aside) and is freely offering His grace to ALL without distinction. That offer of free grace with end one day and God will restore Israel to their place as the head of the nations.
Rom 11:15 (AKJV/PCE)
(11:15) For if the casting away of them [be] the reconciling of the world, what [shall] the receiving [of them be], but life from the dead?
