Why Think the Evidence for the Resurrection Is Strong if Saul Wasn’t Convinced by It?

Questions about why anyone should think the evidence for the resurrection is strong if Saul and the majority of first-century Jews found it insufficient, why Jesus came to to the Jews rather than another nationality, and how other nationalities came about through Noah.

• Why did Jesus come specifically to the Jews rather than to a Chinese family or African or any other nationality, and how did those other nationalities come about through Noah?
