So, do you believe Jews are saved? Is there an alternative to redemption through Jesus Christ?
Jesus Himself said: "I am the way, the truth, and the life - no one come to the father except through Me" (John 14:6)
Jesus was either:
lying,
insane,
or really if the only way.
Your question poses a false premise never implied in the post you responded to. There is only one way and it is through Jesus.
A Jew can only go to God through Christ, yes most Jews will be condemned just like most gentiles, none of this is mutually exclusive.
