One could ask the same about Jesus of Nazareth ( whose actual name was Yeshua, according to many experts). Seriously, Jesus’ claims were seen at the time as being quite outlandish and even dangerous, rather than quirky. So what was HIS motivation? Other than he really was the divine son of God who came to die for our sins. And if that’s true, then what are these modern day second comings of Jesus prepared to sacrifice? There are billions more sinners to account for!
