Yes, that is precisely my point. The Jews have decided to just say that "the Lord turned a curse into a blessing." So when you hear the same sort of argument used against Jesus, just remind them of their own little problem.
Believing in God is a spiritual condition. Being a Christian is a spiritual condition. Being Jewish is a spiritual condition. You don't catch it from your mother or your father, only from God.
This is kind of off topic but can you recommend a good translation/version of the Tanakh? I have a JPS version but I don't think that one is very good.
Thanks.
