I'd be skeptical about believing anything from a "Jew for Jesus". If they can't be honest enough to just call themselves Christians, why should they be believed on any other subject?
Christ told us we would be reviled for telling the truth about Him.
No surprises here. My only concern is that the Godless Yankees will win the pennant....
Just say, "Our brand of Christianity thinks ANYONE who isn't a believer in Jesus as God's resurrected Son is doomed."
That should settle everything for any adult in America.
Sadly, you might be dealing with those who aren't adult enough to realize that any religion has its own beliefs.
Do Jews believe Christians will go to Heaven?
Blessed are those who are persecuted for Jesus's sake. Historically, persecution has been the norm for preaching the truth.
