Not sure the God of the Omnis is a always a good match for the God of scripture and omnibenevolence is always going to present problems since it is categorically different from the other omnis.
Firstly, it should be said that there is no single "God of scripture" - the one obvious thing about It is that it appears in a different guise with every prophet and evangelist. Secondly, the particular god you're inviting us to believe in (who seems to derive from philosophical speculation) appears to have no relation to the various guises of the 'divine It' in scripture at all. What has the tribal Yahweh got to do with this 'point on which all the hierarchies depend' after all? And Jesus called his god (who was also somehow himself) "Daddy" - how does that correlate with what you're saying? Jesus also apparently identified with the tribal Yahweh, since he referred to Noah, Abraham and Moses as seminal figures in God's revelation, apparently culminating with himself.
I’m not sure omniscience necessarily suggests foresight. Does God know because he can see at one point in time with 20/20 vision or accuracy into his future., or does he know because he’s actually there at that moment...?
Maybe he's learning (Process theology)
P.S. I note that our old returning friend Stranger has said something like my first paragraph too.
PPS.
This is from Milton's Paradise Lost, Book 7.
You can interpret it for us.
I don't know if it helps your cause at all:
"Boundless the Deep, because I Am who fill
Infinitude, nor vacuous the space.
Though I, uncircumscribed myself, retire,
And put not forth my goodness, which is free
To act or not, Necessity and Chance
Approach not me, and what I will is Fate."
