The separation of Israel from the other nations begins in Genesis 12:1. Abram is to be the first of the nation of Israel so he is told to leave his country (the region of Ur and that of Haran), his people (his ethnic group) and his father’s household (his extended family identified in the genealogy of chapter 11). Abram is isolated so that he can develop and be unique free from residence and oppression
from his culture.

Abram’s wife’s name, Sarai, was the name of the moon god’s consort, and it means “princess” in Hebrew and “queen” in Akkadian. Lot’s sister’s name (the wife of Abram’s brother, Nahor) was
Milcah and it means “queen, the title of the moon god’s daughter.’ Joshua 24:2 and 24:15 clearly says Abram’s father, Terah, was a worshipper of the moon god. If Abraham had stayed in his
region among the ethnic group he would have been expected to continue participation with this father’s household in the community’s worship of the moon god. If Abram had refrained because
of his allegiance to the Lord, any disaster or hardship that the people of Haran or in his father’s household faced would have been traced back to Abram’s lack of devotion to the moon god.
Abram had to leave; there could be no mixing of the past with the future.

Not only did God call Abram, but he also gave Abram his Word. God made promises to Abram
that would extend through Abram’s life and far into the distant future. And, these promises were
not merely words of blessing to Abram and curses on the idol worshiping nations. These were blessing to Abram with the purpose of blessing the other nations with redemption and restoration.
The phrase “All peoples on earth will be blessed through you,” means the people of the nations
will “find or obtain blessing” through Abram and the promises God has made to the one he
called out from the nations.

Atheism rejects the existence of God (or, theism) because it is felt there is no enough evidence to prove God exists.  But, this erroneously leaves the impression that there is proof that God does NOT exist. Saying, “No one can prove God exists!” is not the same thing as saying, “We can prove God does NOT exist.” It is logically impossible to say, “It has been proven that God does not exist,” because not every option has been examined and not everything thing is known. It is more reasonable and the evidence is manageable to show the existence of God. First, life does exist. Second, life must originate from God’s special creation or by chance life emerged out of the chaos. Does life exist because of God or chance, or is there a third option? It is provable that life does not come from chance, so the only option is that it comes from God since there is not third alternative. Atheism is illogical, while theism is based in logic.
