I have neighbors that are charismatic (I think; they were formerly Baptist), that seem to be worshippers of the Jewish people,

Many of the Jews who rejected Jesus did so because they had turned their own bloodlines into an idol.

John the Baptist addresses this.

Luke 3:8

Therefore bear fruits worthy of repentance, and do not begin to say to yourselves, ‘We have Abraham as our father.’ For I say to you that God is able to raise up children to Abraham from these stones.

Well said.

“Many of the Jews who rejected Jesus did so because they had turned their own bloodlines into an idol.”

That’s exactly it to put it simply. Jews don’t believe in an afterlife, they believe in promoting the continuation and exaltation of their race. This goes against the teachings of Christianity on so many levels I just can’t fathom how some Christians want to relate the two religions as being intrinsically connected in their beliefs.
