The word, 'God" comes from a Babylonian Idol for good luck.
In Genesis 1:1, the word Elohim is used which means Mighty One and sometimes it is considered plural.
In Genesis 1:25 Elohim creates man in His image.
Genesis 2, Creation was finished.
Genesis 2 Another man is created by Yahweh Elohim and put in the garden of Eden. In verses 23 & 24 Eve is given to Adam to become one flesh cleaving to each other and fortify the Father, which means Adam was to learn to love all the beautiful attributes of Eve before he sexually joined her.
Genesis 3 Adam is told to not eat of the tree of knowlege - cunning.
When the most cunning creature in the Garden, Adam cunningly decided to get what He wanted without even consulting with his Maker, He in effect decided for himself what is good and evil, not Yahweh. This was in effect a mental murder of Yahweh. And this mental murder was transmitted via his sperm into his first son Cain.
And when Cain was faced with Yahweh's advice vs Cain's own lust, Cain decided for himself to do what he wanted, which was to kill Abel.
And this is the essence of sin ever since, Adam's brats deciding good and evil for themselves as if they were Elohim, regardless of what Yahweh said.
This sort of mental murder continued in Adam's kids even to today. Which is why, "Only the overcomers enter the Kingdom of Heaven" Every person must over come that ancient lust to decide good and evil ourselves.
This is why most people who profess to Be Christians suppose they are more righteous than YahwehShua. (Yahweh Saves)
And the word "Sin" comes from ancent Harran, where Abraham & Yacob dwelt at times. To the Gospel believers of Haran, the Moon was Yahweh's and He had placed a happy smiling face on the Moon, perhaps His own. And so, people who chose to decide right and wrong for them selves, were usurping the place of Yahweh, just as Adam did. thus usurping Yahweh & His Laws came to be called sin.
