Hello, the passage from Romans 11:25-26 in the Greek actually states something very differently. This is how I would render these verses: -
The way I would translate, – “
until the fullness of the Gentiles, has come in, And so all Israel will be saved,” from the Greek text is in this way: –
“that blindness in part has happened to Israel until, with respect to time, the prophesied full time period of the ‘heathen’ Gentiles trampling the sanctuary and the Host of Israel is completed, after which all of Israel will be saved;”
The traditional rendering of these verses introduced replacement theology into what Paul wrote where as Paul's intention was pointing to the time when Israel would be redeemed and enter into renewing the Kingdom of Priests, a Holy Nation and His Possession among the nations covenant which they had rebelled against at Mt Sinai within 40 days of agreeing o that terms of that covenant. Paul was pointing to the 2300 year prophecy having run its full course in time that is recorded in Dan_8.
20 "Thus says the Lord of hosts:
'Peoples shall yet come,
Inhabitants of many cities;
21 The inhabitants of one city shall go to/walk with another, saying,
"Let us continue to go/walk together and pray before/before the face of the Lord,
And seek the Lord of hosts.
I {the Lord of host}, myself will go/walk with {you} also."
22 Yes, many peoples and strong nations
Shall come to seek the Lord of hosts in/who resides in Jerusalem,
And to pray before/before the face of the Lord.'
23 "Thus says the Lord of hosts: 'In those days ten men from every language of the nations shall grasp the sleeve of a Jewish man, saying, "Let us go/walk with you, for we have heard that God is with you."'"
Suggests that the nations will seek out the Jewish people in search of their salvation. In other words, the nations will come into relationship with Christ/God because of the redemption of Israel after the end of this present Age.
Shalom
