Some Jews don't, but true Jews do for as the scripture says, not all Jews are Jews.
Historically speaking it was the Jewish leadership that led to the crucifixion of the Lord Jesus, but many Jews believed.
In fact, the apostles Peter, James, John and even Barnabas and Paul were all believers.
Salvation is for all who believe in the Lord Jesus Christ, that He came, died and and God rose Him from the dead.
For there is no other name given under heaven by which we can be saved.
Jews and Gentiles are included!
