God promises Avram our 1st ancestor:
“I will make of you a great nation,
And I will bless you;
I will make your name great,
And you shall be a blessing” Genesis 12:2
In God’s covenant with Avram, there is no mention of anything religious, God promises Avram to make him a great nation. God will also promise Avram the land, many children, and prosperity.
At its core, Judaism is about peoplehood and belonging to a community!
Being part of the people of Israel.
