The Jews of Jesus’ day believed in Yahweh and that he performed miracles, and they knew their Old Testament prophecies, and yet the overwhelming majority of them did not believe Jesus was raised from the dead by Yahweh. The most plausible estimate of the first-century Jewish population comes from a census of the Roman Empire during the reign of Claudius (48 CE) that counted nearly 7 million Jews. If we add in the Jews outside the Roman Empire in places like Babylon, the total first century Jewish population could have been 8 million. It’s estimated that there may have been as many as 2.5 million Jews in Palestine. By contrast, as Catholic New Testament scholar David C. Sim argues, “Throughout the first century the total number of Jews in the Christian movement probably never exceeded 1,000 and by the end of the century the Christian church was largely Gentile.” (Link) Since the Jews didn't believe why should we? No really. Why should we?
