Honorifics for deities in fantasy settings

We in the real world have plenty of honorifics for royalty and religious figures, like your majesty for a monarch, or your holiness for the pope, etc; but given people can't just normally speak to gods, there aren't any formal honorifics for speaking to them (that I know of, at least).

But, in a fantasy story where direct communication with deities is possible, what would be a good honorific for referring to and talking to them? Looking for any ideas, whether they're your own or examples from popular exisiting settings and stories.

Thanks in advance!
