Ganesha is the one of that pair that removes obstacles. Josh is just a nepo hire.

I've always loved this one, because religious people often give off a real childish "my dad can beat up your dad" vibe

I'm calling this one for Ganesh. That's a dirty kick by JC, but he's already taken some big hits, and there's more on the way. Once Ganesh starts with that axe, which would normally be out if the rules, but anything goes in this Gods' Grapple showdown, it's all over.

If they were both praying to Jesus, does one Jesus wear a different color outfit when they fight?

Even Ganesha's mouse is getting involved.

What if they both pray to the same god

Don't worry, there are over 9000 gods, but only yours exist

I need to understand this. Can someone point me in the right direction?

depends how much people is worshipping to both, the more worshippers the more power the god has.
