I mean he is omnipotent and omniscient. If you are omnipotent then there are no challenges, and if you are omnisciet then there are no surprises.
Take us humans for example. He created us, gave us freewill and let us run amok. So he got over the omnipotent part by freely giving it up (giving us freewill, at least for a while), but he’s still omniscient; he knows who of us will fail and who will succeed.
So maybe he hazed his own sight, it would be the only way for anything to ever happen beyond himself.
Or maybe he created us out of love knowing that he would never himself truly benefit from us as we cannot give him anything (as he is omniscient and omnipotent he could merely create being who love him; angels).
There are some explanations that suggest that each of us is simply God playing hide and seek with himself, that each moment is a surprise as the players in an ad hoc play move back and forth upon the stage…
What you have written, and what has been answered suggests that we haven’t much idea about God and that the metaphors and allegories we have are not comprehensive. It wakes the idea in me that the quest has only just begun, even though we seem to have little time…
Perhaps we should broaden our horizons and accept that God is the ineffable, but that we should start to understand ourselves a little better.
Maybe god just likes to watch us have personalities… I don’t think God can have one for himself… so maybe he just likes watching characters… be is a rapist or a… priest rapist… he’s facinated by it all.
