God is more of a concept rather than entinity. Terms like learning and surprise do not really apply.
Yes, they do.
One of the fundamental concepts of
theistic faith (of which Christianity is a crowning example) is that said deity is a "
personal god", to whit, a god...
...who can be related to as a person instead of as an "impersonal force", such as the Absolute, "the All", or the "Ground of Being".
If we can talk about god as a person or entity, then questions such as whether said god learn are indeed relevant.
A god who can be thought of more as a process or concept sounds like a pantheistic god, which was not what I was asking a question about.

S'interesting stuff, really.
Yeah, it was kind of niggling away at me. That said, this sort of stuff is why I'm interested in the topic in general; you can argue existence till you're blue in the face, and get nowhere. Far more interesting are the properties and constraints such an entity would have.
E: That said, I imagine the more lay understanding would be that god could learn, but has no need to, as you mentioned. No reason, as all the decisions or knowledge god could wish to make or have is already known to god, so the general stuff that prompts humans toward learning or changing opinion simply isn't there.
As for change... maybe. From what I understand, that's somewhat underpinning the difference between new and old testament. Though it might be arguable that god did not change, merely the covenant god has with man, or whatever that is. Exactly where a person falls on it probably differs between denominations and religions, assuming they've ever really thought about it at all.
The Old/New schism is what got me thinking about this question to begin with; I think we can all agree that there is a pretty big shift in tone between the two, which then raises questions as to why. Not going to lie, as an atheist my suspected reason is a pretty simple one, but that doesn't mean I can't evaluate other possibilities.
I came up with the following alternates to the first option:
God is not omniscient; and is capable of making false starts, and thus learning.
God is not omnipotent; and you have alternate conflicting influences.
God needed to act like a homicidal maniac to begin to influence the crowd of the day, but once an established presence was made, more passive teachings could proceed.
Or, the act of god imparting himself into an earthly vessel altered his perspective on the matters somewhat.
Ahh well.
