Individually Jews can come to Jesus and become part of the Bride of Christ. (See III. A. 3 and 4 above), although as a nation they are blinded because their rejection of Jesus hardens their hearts.(SEE APPENDIX W).
Rom 11:7-10 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.”
Isa 6:9-10 He said, “Go and tell this people: “`Be ever hearing, but never understanding; be ever seeing, but never perceiving.’ Make the heart of this people callused; make their ears dull and close their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts, and turn and be healed.”
