I do not see how your study of the word 'all' changes the truth that Jesus will draw all to himself. Jesus died for the sins of the WHOLE world. 1 Timothy 4:10 (and for this we labor and strive), that we have put our hope in the living God, who is the Savior of all men, and especially of those who believe.
1. I know its a bitter pill to swallow for many Christians. It was for me. But I could not cover my ears and close my eyes to the truth. I cannot find any passage(s), in its proper context, that state Christ came to save non-Israelites in this age. Perhaps in the Judgment period (Rev 20:11-12).
This doesn't mean all Christians are doomed. Most, if not all, of them could be descendants of Jacob and not even know it. As a matter of fact, DNA technology suggests most people in the world have Israelite ancestry. Which makes most of the world's population Israelite! This theory is strengthened by God's promise to Jacob to number his descendants as the sands of the sea (Gen 32:12).
As far as your verse above, once again "all" is qualified to mean all Israelite men [and women] especially those who believe. Notice:
Luk 6:26 Woe to you when all men speak well of you, For so did their fathers to the false prophets.
This is the sermon on the mount. Jesus was speaking to Jews. There were believing and non-believing Jews. Once again, the "all men" is actually referring to "all Israelite men" because their 'Israelite' fathers were the only ones qualified to be prophets!
1 John 2:2 He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world [kosmos-G2889].
2. Just like the term “all”, the term “world” is also qualified by its immediate and broader context. It can refer to the adornment of woman's hair (1Tim.2:9) where "kosmos" is translated as ["modest"]. It can include the “world” of---either order or disorder, fame and honor, the orderly universe, the stars in the universe and even heaven. James refers to the tongue as, “a world of iniquity” (Jam 3:6).
It can mean the whole world of wicked and reprobate men e.g., “world of the ungodly” (2 Pe 2:5) as opposed to the "world" of the godly or God's elect/chosen
John 12:19 The Pharisees therefore said among themselves, "You see that you are accomplishing nothing. Look, the world [kosmos-G2889]has gone after Him!"
The ‘world’ who went after Jesus certainly excluded the Jewish Pharisees who uttered the words. It also excluded Jewish unbelievers and every one else who was not there. So it could no refer to every person in the ‘world’. The term could only refer to believers who at the time consisted of Jews exclusively! Based on the context the term could have been rendered, “the world of the Jews”.
When encountering the term “world”, we must ask whose world or what type of “world” is meant. When we remember that both houses of Israel were separate groups scattered among the nations of
the “world”, this is easily understood.
One thing to remember, because of the split Israelite kingdom (house of Judah and house of Israel) the Jews only consisted of Judah and Benjamin. So when you see the term 'Jews' in the NT, it refers to only people of those two tribes.The other ten tribes Jesus referred to as" the lost sheep of the house of Israel" (Mat 10:6) were scattered throughout the nations. Peter and James' epistles are directed not only to the house of Judah--Jews-- but also to the house of Israel, who were scattered throughout the 'gentiles' and commonly referred to as 'gentiles' in the NT. God promised to scatter the house of Israel into the 'gentiles' [nations] so they lose their identity as Israel. He is now regathering them through his NT church:
Hos 7:8 "Ephraim has mixed himself among the peoples; Ephraim is a cake unturned.
Hos 8:8 Israel [ten tribes] is swallowed up; Now they are among the Gentiles Like a vessel in which is no pleasure.
Eze 4:13 Then the LORD said, "So shall the children of Israel eat their defiled bread among the Gentiles, where I will drive them."
Eze 12:15 "Then they shall know that I am the LORD, when I scatter them among the nations and disperse them throughout the countries.
Amo 9:9 "For surely I will command, And will sift the house of Israel among all nations, As grain is sifted in a sieve; Yet not the smallest grain shall fall to the ground.
Psa 106:27 To overthrow their [Israel’s] descendants among the nations, And to scatter them in the lands.
I hope you are not suggesting that everyone from a specific race are going to be saved.
3. No. God is impartial to race or color. Race is a modern concept. The ancients did not did not divide people according to physical differences, but according to
religion, status, class, even language. God is partial to Israel’s religion. Contrary to popular opinion, the religion given to Moses at Sinai is not the Judaism we see today.
He has mixed in Jacob's seed with all the races of the world so Israelites consist of all races and colors today. What God is partial toward is ancestry. DNA has revealed a person perceived to be a non-Jew can share the same ancestry as the Israelites! God is only interested in saving Israel’s descendants who today can be disguised as Americans, Europeans, Africans, (name your ethnic group, race, color, nationality).
Paul was letting the believers know that the Jews were not cut off forever...that within the Jewish community---there are true believers who will come out of her and will be saved. It must have seemed as if God cut off all Jews forever. If God had cut off all Jews forever, then SOME TRUE BELIEVERS will be cut off forever. Since that is not the case---all Israel (meaning all true believers) will be saved, because not a whole race of people will be cut off.
4. Paul reveals the ancestral identity of the ‘believers’ you speak of in the beginning of his letter to them:
Rom 4:1 But if so, what can we say about Abraham, our forefather by natural descent? (Moffatt)
Paul identifies the ancestry of his audience then and today, as he uses a first person pronoun to identify the physical ancestry of all members (both Jew and gentiles) of the Roman congregation. Like Paul, they were all physical descendants of Jacob through his grandfather Abraham!
