Paul was an ardent anti-christian. As the story goes he was on his way to Damascus to arrest some folks for being blaspheming christians. Jesus stops him on the way and forces him to become a believer.

There are a lot of non believers that never get this sort of treatment from Jesus. If it is necessary to be a believer for salvation, why are not all non believers confronted this way? Paul wasn't just a non-believer he was an anti Christian and yet Jesus gave personal attention to his error.

Why doesn't Jesus do the same for say Richard Dawkins or Ali Khamenei? But more to the point, considering the obvious ineffectiveness of human evangelism, why does Jesus not personally confront everyone who doesn't have the right belief?
