Okay, what would you have advised those Jews that were faced with accepting this Jesus of the NT or rejecting him?
The only Jesus they would know about is the Jesus in the gospels. Would you have believed it? Virgin born, walked on water, cast out demons, raised Lazurus from the dead. So many miracles, how could they not believe that Jesus was from God? Except the even Baha'is say some of those things are literally true.
And then the big one... those Christians trying to convert those Jews tell them that Jesus rose from the dead and eyewitnesses saw him ascend into the clouds. And some angels told them that this Jesus would return in the same way.
More stuff the Baha'is don't believe literally happened. But these Christians were telling these Jews that all these things did happen. Oh, and they told them that Satan is real and trying to deceive them. Another thing Baha'is don't believe is true.
So, what is it that you would advise these Jews to do? Stay with their old beliefs? Or convert and believe this new religion that has messed things up so bad that they also insist that Jesus is God... And have
burned people at the stake that questioned that belief.
