Only because of your own cultural background / upbringing where Josh was a pretty normal and non-reverent name, like how people like me one day realise there's a whole culture of people out there where Jesus is still a common and popular first name, instead of something reserved for a religious figure.
I live in one of those cultures and have several coworkers named Jesus. But some names have different associations. It is like "Todd, The Necromancer!" Vs "Evelyn the sorceress". Jesus is a serious and competent embedded c++ programmer. Josh is a goofy guy in accounting.
