Hmm. I think the “bloodline” has given great power and authority the the tribe of Jacob… I have a feeling that Gods chosen doesn’t mean chosen by the creator of the universe at all, but chosen by the logos of earth.. Yahweh who is also known as Elohim.. at some point these separate Gods got merged into one super being, father of the cosmos as the two ideologies merged and exchanged traditions. This is the start of monotheistic religion. Abraham was a Babylonian, and he learned about God there first, his travels to Egypt let him to call God Elohim, which is the name of the God of Egypt during this kingdom. This I think is where the two Gods became one. Elohim and Yahweh are the same after this period. Even the Muslims took part in this calling Yahweh Allah after the prophet Mohammed emerged and conquered. Yahweh, Allah, Elohim seems to be a waring God, a God of conquest. Nothing like the divine being Yeshua called father. But that’s just my take on the whole thing. I’m still seeking understanding and knowledge in this topic.
