I knew this about you, but I think it beyond one man's capability to reinvent every theological wheel, though some theologians get close. They however, spent little time doing much else.
Probably you are away and/or don't want to discuss further but I will say my piece anyway.
I don't think it is a good reason not to search for truth just because you havent got time for much else. It's your choice. I was only thinking that the fact of your participating in a theological debate forum was an indicator that you were interested. With 'reinventing every theological wheel', you make it sound like debating this is tedious. Again, probably you don't want to join in further. It is your choice.
It is a worthy point to contrast here, and an important one as it reflects on society in Christianity, and at large as well. I do understand your OV thinking behind the sentiment.
Judging from your below comments, I am not at all sure that you do. Because you don't seem to see that there is any self-contradiction in these statements.
For me, "as He want's/needs" expresses a limitation.
God is Almighty (scriptural given of omnipotence). This necessarily means He is beyond utilitarian (needs) or volition (He is powerful and thus 'can' do as He wills with no qualification though I don't have as much issue with 'wants,' just that it may allow for whimsy rather than who He is, all the time).
I only conflated wants-needs because in many languages they are the same word, same concept, just as in English they used to be and I am perfectly happy to assume that anyone reading what I write also doesn't make a hard and fast distinction between them. If it was in God's nature to create the world, then he needed to create the world in order to express that nature. So his nature entailed a need. The reason he wanted to do it (what you call volition) was because he had a need to do it. In modern English-speaking society we say that a person can have urges - instincts, habits, whims (as you say) - but that he is responsible for his actions and if those urges, etc. are harmful to others then he has the ability and the responsibility (if he is adult) to suppress them. This is a deep psychological and spiritual issue at the root of culture and I can only say that I am perfectly happy with the view that want and need are one and the same thing. I think that Christian maturity demands it, otherwise we can always excuse ourselves that we were not in control of our actions. I can only assume, as I am sure you also do, that God is in control of his.
But again, this was what I was trying to separate from God being unable to lie. It isn't a comment on His power, but on the fact that He is by nature against it ever happening.
But you failed in trying to separate it. And if you still insist, then surely you must assume that God's nature is in two distinct parts: the 'soft' part that represents characteristics like love, faithfulness, truth, and a 'hard' part that represents things like the substance God is made of, how many fingers and toes has he got, is he made of a substance called 'spirit' that happens to be everywhere, can he make things out of nothing. The IT analogy will I am sure not be missed by you.
But your problem is that you cannot make such a distinction with God. It is both invented and illusory and serves only one purpose: to enable you to maintain that after all God can do anything at the same time as maintain that there are some things that he cannot do.
It is similar to "Can God make a rock He canno lift?" The answer is neither 'yes' nor 'no.' Rather, the answer is "illogical question." Similarly: Can God sin by sure power? Because it separates Him from His nature, you could say "yes, because He is all powerful" or "No, because He can't/will not do it."
I already referred to that question. But as I previously also intimated, I do not give either answer. The answer is that God cannot do this because God is self-consistent (God cannot deny himself). I know the question is illogical but the reason God cannot do it is because he is self-consistent. People can do illogical things (or at least attempt to). Self-consistent beings cannot.
Perhaps (as I was thinking out loud) the problem is in an illogical or not well thought out question. So, that's about the whole gist of my posted interjections. -Lon (and thanks again for participating).
I hope you will see that it is the (theological) concept of omnipotence that is illogical. Your attempt to separate that from certain aspects of his personality (nature) proves that inwardly you think of omnipotence as being qualified, even if outwardly you say the opposite. You said: "For me, "as He want's/needs" expresses a limitation." This implies your belief that God's character (his wants and needs) are not an integral part of his being, that they are incidental. For me, they are certainly not. If you are into 'pedantic' scripture, then 'God is love' (1 John 4:8) would very much support me here. God's character of love (as an example) is an integral part of his being. If God is unable to do something because he is a god of love and not of hate, then he is unable to do it.
You began with omnipotence as a biblical concept. Biblical omnipotence is relational: it is in relation to the world and to man. There is no justification for saying more than 'God is as powerful as he needs to be in expressing his own plans and intentions, his own unchanging character'.
