The Jews are set aside as a nation, but individually they can still come to Jesus as the Messiah. Their setting aside isn’t permanent, for God’s promises to Israel are unconditional. One day they will reenter the center stage and God’s focus will again be on them. Romans 9-11 tell about this in detail. (SEE APPENDIX W)
Rom 10:1-4 Brothers, my heart’s desire and prayer to God for the Israelites is that they may be saved. For I can testify about them that they are zealous for God, but their zeal is not based on knowledge. Since they did not know the righteousness that comes from God and sought to establish their own, they did not submit to God’s righteousness. Christ is the end of the law so that there may be righteousness for everyone who believes.
Rom 11:1, 7-12 I ask then: Did God reject his people? By no means! I am an Israelite myself, a descendant of Abraham, from the tribe of Benjamin. … What then? What Israel sought so earnestly it did not obtain, but the elect did. The others were hardened, as it is written: “God gave them a spirit of stupor, eyes so that they could not see and ears so that they could not hear, to this very day.” And David says: “May their table become a snare and a trap, a stumbling block and a retribution for them. May their eyes be darkened so they cannot see, and their backs be bent forever.” Again I ask: Did they stumble so as to fall beyond recovery? Not at all! Rather, because of their transgression, salvation has come to the Gentiles to make Israel envious. But if their transgression means riches for the world, and their loss means riches for the Gentiles, how much greater riches will their fullness bring! … If some of the branches have been broken off, and you, though a wild olive shoot, have been grafted in among the others and now share in the nourishing sap from the olive root, do not boast over those branches. If you do, consider this: You do not support the root, but the root supports you. You will say then, “Branches were broken off so that I could be grafted in.” Granted. But they were broken off because of unbelief, and you stand by faith. Do not be arrogant, but be afraid. For if God did not spare the natural branches, he will not spare you either. Consider therefore the kindness and sternness of God: sternness to those who fell, but kindness to you, provided that you continue in his kindness. Otherwise, you also will be cut off. And if they do not persist in unbelief, they will be grafted in, for God is able to graft them in again. After all, if you were cut out of an olive tree that is wild by nature, and contrary to nature were grafted into a cultivated olive tree, how much more readily will these, the natural branches, be grafted into their own olive tree! I do not want you to be ignorant of this mystery, brothers, so that you may not be conceited: Israel has experienced a hardening in part until the full number of the Gentiles has come in. And so all Israel will be saved, as it is written:
