How did Paul the persecutor of Jewish believers become a believer?

Les explains that Paul had persecuted those early Jewish believers back in the book of Acts, and then God saved him by grace on the road to Damascus. After that, God took him down into the desert and revealed to him over what Les thinks is a three-year period the amazing doctrines of grace. Les notes this put a block between Paul and the Jewish people, because Saul of Tarsus was one of their own, taught at the feet of their most famous rabbi. When he came back from those revelations, he told the world they were not under the law, did not have to circumcise their children, keep the law, go to the temple, or sacrifice animals—all of that had been set aside. Religious Jews therefore thought he was nuts.
