This is touted as a compelling reason Christianity is believable, but I find it sorely lacking. People convert, even antagonistic people. It happens all the time. Some people even call them traitors. Such conversions prove nothing. It's even a Hollywood trope, yet notice how none of the plots of those movies felt the need to invoke the supernatural to explain the protagonist's change.
It is interesting to note that Jesus didn't condemn homosexuality, but for some reason, Paul of Tarsus decided to make a point of it.
