The Bible has a grounding in the idea that Gods Will and our desire to persist against the amoral backdrop of Gods creation is one and the same. Human values such as birthright, tradition, rules and regulations are a tool but not an end according to the Bible. By paying attention and not falling into the illusion of political power, materialism or egotism we can survive and thrive. It is at its heart an idea as elegant as any which does not need to carry any baggage . But those who believe the Bible literally have mistaken the Word for the baggage IMO.
The story, the rules they point to God, but they do not define God except in contradictory ways which the authors often cleverly incorporate through their method of using story. This raises our understanding of God to the highest level...that of capturing in words that which is ultimately a mystery.
To this biblical account there is a kind of parallel support. In the Old Testament
the support for the text was in LAND. That is, the Jewish people measured their
relationship with God by gaining or losing land. Jacob said the Jews would lose
that land when the Messiah came - and Jesus himself said the same.
Thus you could argue with the bible, but you couldn't argue with the historic
account of Israel.
And for the New Testament I suggest that parallel confirmation is the account of
the Jews - driven out and persecuted, but by amazing events they were able to
return to their ancient land when the Gentiles faith was gone.
Thus you can say the bible is myth, but it was quite prescient about those once
considered God's people, and their rise and fall in relationship to the Gentiles.
