[Ali Imran]

No, Paul did not teach that believers should completely discard the law. While he emphasized that salvation is by grace through faith and not by adherence to the law, he also affirmed the law's continuing value in revealing sin and guiding Christian behavior. He clarified that the law's purpose was not to save, but to point to the need for a savior and to guide believers in righteous living. 

So look at that Pink. Your friend already admitted that Paul's teaching is not the same as Jesus's teaching.

Jesus said salvation includes adherence to the Law.

So, going by your criteria, it wasn't Jesus who visited on the road to Damascus.
