I could ask you the same question Tansy. Both Vekky & I have made numerous posts that prove otherwise. You are still living (or stuck) in the OT, as though the New Covenant was never ratified by Jesus' precious blood.
If you believe Israel are still God's 'chosen ppl', then you have yet to understand one of the central tenets of your faith - that there is only one gospel, one saviour, and one community of the redeemed - aka the body or bride of Christ, aka the church 'militant', made up of believers from all the nations on earth, including Israel.
There is no alternative route to salvation specially reserved for any nation - not even Israel.
