The Jews who rejected Jesus were scattered to the four winds as punishment by God.
They were punished time and again.
For any Christian to think it's good to help the Jews who refuse to repent is nothing less than an abomination.
Jews need Jesus too yet you follow an unrepentant people to hell rather than give them the truth.
Such Christians have not the Love of the truth in them and will be delivered into damnation.
Jesus did not come just for the salvation of the gentiles, he also came to save the Jews.
Thus until they repent we are to as we are told:
11 And have no fellowship with the unfruitful works of darkness, but rather reprove them.
You cannot be a Christian and Coddle people in their evil ways.
