Sounds like a cool set up for some world building! I think it’ll depend on the religion how people organize under that religion, social norms, who the deity is, what the deity believes and what the character talking to the deity believes.
For example: I am catholic. The catholic religion is really strict about god being omnipotent And all powerful and humans are not deserving of his love, however, because of what I believe, if I got to talk to Jesus, the son of god in the catholic religion, from the stories of him that are written in The bible which is our religious book, I believe he’d be a really cool person, like treats kids with love and respect, washes peoples feet, loves his mom, yah the guy sounds pretty laid back and a nice person. I would call him Jesus rather than ‘son of god’ or something like that because of all those world building factors I mentioned below. I definitely recommend looking at this because it could be some great opportunities to define your reality in your story ^*
