If I were a Calvinist, that wouln't be a problem. Since I'm not, it is, but not a hard one. As your ally Vercingetorix notes, the Jews were expecting a military leader, not a sacrificed Lamb. The religious leaders of the day had been attacked by Jesus and put him to death, and they led the people against Christianity. The people had called for Barnabas to be saved, not Jesus. But this predisposition against Christianity is nothing next to what would exist if there were no such person as Jesus. If that had been the case, no one could have taken Christianity seriously, let alone converted to it, let alone died for it.
