In the Greek lexicons. in the 2nd line the true God is called a Greek word that ends in v=God--The Logos is called the Greek word that ends in g=god. 100% proof that is how that gets translated = 2Cor 4:4--Satan= the god of this system of things called the Greek word that ends in g=god and the true God called the Greek word that ends in v=God. These are facts.

Do you know what I mean when I say, "the lexical form" of a word? This is the basic root form of a word.
Ho Theos is the lexical form, and means, God. Ho is an article, not always translated, but belongs with the noun. Depending on the context ho theos may be translated either "God" or "the God", with or without the capital, as there is no capitalization in the original.
Ton Theon, as you see at the end of verse two, is the same word, with the same meaning, but is in the "accusative" form. This means that it's receiving the action of the verb.
In English, we show this by word position. "I threw the ball." "The ball" appears after the verb, so we know it receives the action. I threw something, it was the ball that was thrown.
In Koine Greek, instead of using word position to show this, they used word spelling, which allowed them to put the word in any part of the sentence they wanted to. Often Koine Greek writers would put their most important parts first for emphasis.
If I were wanting you to know first and foremost that the ball was thrown, I could say "The ball I threw." In English, this reads like a sentence fragment, because we rely on word order, but in Koine Greek, it's a perfectly good sentence. The "on" ending, "ton theon" lets us know this.
Are you with me so far?
What I'm saying here is that ton theon and ho theos are the same word, only, one has the different ending to show it's receiving the action of the verb. It's purely for grammatical syntax, not to alter the word meaning beyond that.
In this case, John wrote, the Word was toward God, and God was the Word. In that first instance, "God" receives the action of the Word being towards, so, ton theon, while in the second case no such distinction is needed, so, ho theos.
What you called a "g" is the ending form of sigma, our "s".
Much love!
