that ending is 2P2P, which is not in the Bible.
'How can we be grafted in'? Easy! Don't you realize the whole picture is about faith vs unbelief? People stand by faith, v20. You have ethnos conphused with faith! The very opposite of what he is trying to say. this is why those in Israel who believe are grafted back in v23. (I'm putting are instead of will be, because you think he is predicting when he is not; he is talking about current circumstances).
It is indeed a mystery that more Jews don't believe (talked about since 3:3). That is what he means in v25. He doesn't mean there is a mysterious snapshot of total belief coming in Israel. Because all of that surrounding the quote of Isaiah 55 is already happening--the Redeemer, the removal of sins and the new covenant.
I don't see anything in the Rev or ordinary letters about 1 rule in heaven and 1 on earth. The next event is the worldwide judgement of all individuals through Christ and either the NHNE or the gloom of hell after that.
I don't generate doctrine from the Rev if it is not clear in the letters, although I don't see where it matters in this case anyway.
All Israel gets saved, but its the one by faith like in the paragraph about the grafting. It is not the ethnos. No ethnos as such will be saved.
You don't see because your doctrine acts like blinkers for example Paul says
For the creation waits with eager longing for the revealing of the sons of God for the creation was subjected to futility not of it's own will but by the will of Him who subjected it in hope.
because the creation itself will be SET FREE from it's bondage to decay and obtain the glorious liberty of the children of God.
We know that the creation has been groaning in travail together until now, and not only creation but we ourselves who have the first fruits of the Spirit.
Your eyes just skate over scriptures like that...the creation is to be set free, the curse will be lifted. No loud bangs, no melting away of the elements etc....not at that point of time at least, those things happen after the thousand years.
Peter full of the Holy Ghost at Pentecost said
Heaven must hold [Christ] until the time for establishing all that God spoke by the holy prophets of old.
That is that nations will beat the swords into plowshares etc
Those prophecies must come to pass, you can't just take them out of the bible.
You say that it is happening now..where is it happening? which nation is it that does not study war any more? you say the church, but the church is not the nations....we never had any swords to beat into plowshares.
You don't see the prophecies concerning the nations which will flock to the mountain of the Lord to learn the ways of the God of Jacob? really? It is because you read with the view to making the bible agree with your doctrine.
The latter days that Isaiah prophesied are the opposite to the end of the age that Christ foretold, neither has fully happened yet, we see only the birth pangs of the tribulations Jesus predicted.
But Isaiah prophesied peace and abundance.
They are both true prophecies but to be fulfilled at different times
And Jesus said His signs were for the end of the age, not the end of the world.
