Why does ANY culture practice similar morals? Are you aware of history at all???<quoted text>
My assertion is the fact that these are disparate stories which have been woven together. From a literary POV, The Law of Moses cannot exist before his time, yet the Bible states that Abraham keeps the laws and commandments which are pretty much unspecified. There are no laws at the time Genesis takes place, yet there are transgressions of the Law of Moses which does not exist. Why should anyone take any of this seriously? It doesn't make any sense. There is a non-existent moral code implied yet unspecified. It is a teaching story about a vengeful God unworthy of worship. This is not the God of unconditional love introduced in the Gospels.
Do you know most people have a conscience?
Moreover, you have absolutely no understanding of the God of Jews and Christians by your last statement. How do you explain the Psalms if Jews viewed God as a vengeful God?
