Correct my OT Belief

I have found it difficult to overcome the sense that God is himself capricious. In the Old Testament, the writers mention God in a way that describes natural disasters and disastrous miracles in  a manner that makes God seem to have a personality trait associated with emotional outrage. 

While written thusly, and I'm not denying it, I find it difficult to imagine a beautiful and loving creator to have a flaw. We are informed that all of nature screams out that God exists. When I look at nature, which can be terrible, all I see is beauty. 

(In fact, recently, I have begun to see the works of mankind as more natural and beautiful than I once did, but that's for another time.)

To react callously and overmuch so, which God is purported to do, I feel misrepresents his innate qualities. This florid language must be such to relate God to us. (RE: The great flood, Sodom and Gomorrah, the ten plagues, etc.)

This (to follow but not immediately after) is what I feel is intimated, after much study and thought, and if incorrect, I wish to be re-educated as to how to reconcile a God in-line with the laws of nature and beauty with one who is childish and wrathful. He cannot be so.

Yes, we have Jesus who made amends for us and yes I understand that meant our sin is essentially forgotten. I understand sin. But these are all complex concepts and metaphors, the knowing and classifying of which does not diminish the weight and import therein. 

I understand there to be laws of nature as pertains to right and wrong. As in, I understand from the Bible that right and wrong denote ways of living that are essentially for or against nature itself and requiring reconciliation in a natural sense. I posit that. 

I suppose or I interject that the personality trait of childish wrath is misunderstood by me and when I read it, I am wrong at the source. it clearly stands to me to be written that God executes wrath in the Old Testament, wrath in relation to sin against him personally. 

Maybe I am being poetic, but I imagine personal insult to God to mean, on at least some level, to be antithetical to the laws of nature. And, it seems, to reconcile anything unnatural/incorrect, one has access only to specific avenues at specific times (ones that might seem irrational or odd, like eating unclean animals or the slaughter of thousands). 

To reiterate, I find that right and wrong are ways of teaching us how nature works. How the world itself, the universe itself functions. How we function. How interaction functions. How behavior influences the environment (and impacts us personally). 

Right and wrong are as natural, possibly, as the laws of physics that govern how nature is held together. I am supposing that they did not originate with man and with the idea of sin once committed, but that they always existed(since creation itself) and not disparately so from all things at all times, inanimate and animate. 

Of course, the Bible only elucidates what happens when man tries to discern right from wrong, and does not tell us when nature itself is violated any more than that which our actions culminate in. 

Right and wrong absolutely have to be aspects of nature once one reads of God's wrath and that it be poetic representation of the throes of mother nature in correct terminology and origin reference.

If the Bible is literally true, God exists and manifests as fully correct. ('God is righteous.')

I'm not saying I don't believe the Bible, I am showing rationality. Once provided the possibility, it will always be possible (until forgotten). 

Footnote to the footnote: I am not, through lack of saying so, showing I warrant correction as to proper recitation of belief in God in astute church-attuned vernacular. I am being succinct and any 'correction' as to my terminology (for the last two sentences before this footnote to the footnote) would be superfluous rather than remedial. However, it will provoke such in some people invariably. My saying this will do nothing to change that. 

(I am in a very silly mood and cannot speak any less incoherently. Sorry for the turning from plain terms to highly incongruous and cringe-worthy hard to parse sentences.)
